NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021 (EOG's 2020 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the three and six months ended June 30, 2021, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2021, EOG adopted the provisions of Accounting Standards Update (ASU) 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12). ASU 2019-12 amends certain aspects of accounting for income taxes, including the removal of specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and updates to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. The effects of ASU 2019-12 applicable to EOG were all required on a prospective basis. There was no impact upon adoption of ASU 2019-12 to its consolidated financial statements or related disclosures.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

2.    Stock-Based Compensation

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Lease and Well	$	11	$	15	$	25	$	30
Gathering and Processing Costs	1		1		1		1
Exploration Costs	5		7		11		14
General and Administrative	14		17		29		35
Total	$	31	$	40	$	66	$	80

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provided for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

EOG's stockholders approved the EOG Resources, Inc. 2021 Omnibus Equity Compensation Plan (2021 Plan) at the 2021 Annual Meeting of Stockholders. Therefore, no further grants were made from the 2008 Plan from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, SARs, restricted stock and restricted stock units and other stock-based awards, up to an aggregate maximum of 20 million shares of common stock, plus any shares that are subject to outstanding awards under the 2008 Plan as of April 29, 2021, that are subsequently canceled, forfeited, expire or are otherwise not issued or are settled in cash. Under the 2021 Plan, grants may be made to employees and non-employee members of EOG's Board of Directors (Board). EOG's policy is to issue shares related to 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

At June 30, 2021, approximately 20 million shares of common stock remained available for grant under the 2021 Plan.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $9 million and $15 million during the three months ended June 30, 2021 and 2020, respectively, and $19 million and $29 million during the six months ended June 30, 2021 and 2020, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2021 and 2020 are as follows:

	Stock Options/SARs						ESPP
	Six Months Ended June 30,						Six Months Ended June 30,
	2021			2020			2021			2020
Weighted Average Fair Value of Grants	$	20.73		$	16.94		$	14.69		$	20.80
Expected Volatility	46.40		%	42.10		%	54.99		%	35.24		%
Risk-Free Interest Rate	0.36		%	0.93		%	0.09		%	1.56		%
Dividend Yield	2.87		%	1.94		%	3.41		%	1.56		%
Expected Life	5.2 years			5.1 years			0.5 years			0.5 years

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

The following table sets forth stock option and SAR transactions for the six-month periods ended June 30, 2021 and 2020 (stock options and SARs in thousands):

	Six Months Ended June 30, 2021			Six Months Ended June 30, 2020
	Number of Stock Options/SARs	Weighted Average Exercise Price		Number of Stock Options/SARs	Weighted Average Exercise Price
Outstanding at January 1	10,186	$	84.08	9,395	$	94.53
Granted	14	64.97		16	58.40
Exercised (1)	(239)	69.85		(23)	69.59
Forfeited	(234)	91.54		(389)	91.39
Outstanding at June 30 (2)	9,727	$	84.23	8,999	$	94.66
Vested or Expected to Vest (3)	9,421	$	84.91	8,670	$	94.67
Exercisable at June 30 (4)	6,023	$	97.08	4,963	$	94.61

(1)The total intrinsic value of stock options/SARs exercised during the six months ended June 30, 2021 and 2020 was $3.0 million and $0.4 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the exercise price of the stock options/SARs.

(2)The total intrinsic value of stock options/SARs outstanding at June 30, 2021 and 2020 was $114 million and $0.1 million, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at June 30, 2021 and 2020 was $106 million and $0.1 million, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at June 30, 2021 and 2020 was $16 million and zero, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 2.7 years.

At June 30, 2021, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $37 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 years.

Restricted Stock and Restricted Stock Units. Employees may be granted restricted (non-vested) stock and/or restricted stock units without cost to them. Stock-based compensation expense related to restricted stock and restricted stock units totaled $21 million and $24 million for the three months ended June 30, 2021 and 2020, respectively, and $45 million and $49 million for the six months ended June 30, 2021 and 2020, respectively.

(1)The total intrinsic value of restricted stock and restricted stock units released during the six months ended June 30, 2021 and 2020 was $38 million and $13 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the restricted stock and restricted stock units are released.

(2)The total intrinsic value of restricted stock and restricted stock units outstanding at June 30, 2021 and 2020 was $352 million and $217 million, respectively.

At June 30, 2021, unrecognized compensation expense related to restricted stock and restricted stock units totaled $133 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.3 years.

Performance Units. EOG grants performance units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the performance units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the performance units granted could be outstanding. The fair value of the performance units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the performance unit grants totaled $1 million for each of the three months ended June 30, 2021 and 2020 and $2 million for each of the six months ended June 30, 2021 and 2020.

8.    Commitments and Contingencies

There are currently various suits and claims pending against EOG that have arisen in the ordinary course of EOG's business, including contract disputes, personal injury and property damage claims and title disputes. While the ultimate outcome and impact on EOG cannot be predicted, management believes that the resolution of these suits and claims will not, individually or in the aggregate, have a material adverse effect on EOG's consolidated financial position, results of operations or cash flow. EOG records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.

9.    Pension and Postretirement Benefits

Pension Plans. EOG has a defined contribution pension plan in place for most of its employees in the United States. EOG's contributions to the pension plan are based on various percentages of compensation and, in some instances, are based upon the amount of the employees' contributions. EOG's total costs recognized for the pension plan were $25 million and $21 million for the six months ended June 30, 2021 and 2020, respectively. In addition, EOG's Trinidadian subsidiary maintains a contributory defined benefit pension plan and a matched savings plan, both of which are available to most of its employees of the Trinidadian subsidiary, the costs of which are not material.

Postretirement Health Care. EOG has postretirement medical and dental benefits in place for eligible United States and Trinidad employees and their eligible dependents, the costs of which are not material.

10.    Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at June 30, 2021 and December 31, 2020, and did not utilize any commercial paper borrowings during the six months ended June 30, 2021 and 2020.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-capitalization (as such terms are defined in the Agreement) of no greater than 65%. At June 30, 2021, EOG was in compliance with this financial covenant. At June 30, 2021 and December 31, 2020, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at June 30, 2021, would have been 1.00% and 3.25%, respectively.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

Common Stock. On February 25, 2021, EOG's Board increased the quarterly cash dividend on the common stock from the previous $0.375 per share to $0.4125 per share, effective beginning with the dividend paid on April 30, 2021, to stockholders of record as of April 16, 2021. On May 6, 2021, EOG's Board declared a special cash dividend on the common stock of $1.00 per share in addition to a quarterly dividend of $0.4125 per share. Both the special cash dividend and the quarterly cash dividend are payable on July 30, 2021 to stockholders of record as of July 16, 2021.

11.    Fair Value Measurements

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at June 30, 2021 and December 31, 2020 (in millions):

	Fair Value Measurements Using:

See Note 12 for the balance sheet amounts and classification of EOG's financial derivative instruments at June 30, 2021 and December 31, 2020.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) significant Level 3 inputs, including future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At June 30, 2021 and December 31, 2020, respectively, EOG had outstanding $4,890 million and $5,640 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,654 million and $6,505 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

12.    Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of June 30, 2021. Crude oil and NGL volumes are presented in thousand barrels per day (MBbld) and prices are presented in dollars per barrel ($/Bbl). Natural gas volumes are presented in million British Thermal Units per day (MMBtud) and prices are presented in dollars per million British Thermal Units ($/MMBtu).

Commodity Derivatives Location on Balance Sheet. The following table sets forth the amounts and classification of EOG's outstanding financial derivative instruments at June 30, 2021 and December 31, 2020.  Certain amounts may be presented on a net basis on the Condensed Consolidated Financial Statements when such amounts are with the same counterparty and subject to a master netting arrangement (in millions):

		Fair Value at

Crude oil, NGLs and natural gas derivative contracts -
Current portion	Assets from Price Risk Management Activities	$	—	$	65
Noncurrent Portion	Other Assets	—		1
Liability Derivatives
Crude oil, NGLs and natural gas derivative contracts -
Current portion	Liabilities from Price Risk Management Activities (1)	$	396	$	—
Noncurrent portion	Other Liabilities	14		1

(1)    The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $430 million, partially offset by gross assets of $34 million, at June 30, 2021.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposures to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net liability position at June 30, 2021 and a net asset position at December 31, 2020. EOG had $107 million of collateral posted and no collateral held at June 30, 2021, and had no collateral posted or held at December 31, 2020.

13.  Acquisitions and Divestitures

During the six months ended June 30, 2021, EOG paid cash for property acquisitions of $92 million in the United States. Additionally, during the six months ended June 30, 2021, EOG recognized net gains on asset dispositions of $45 million and received proceeds of approximately $146 million primarily due to the sale of its China operations during the second quarter of 2021.

During the six months ended June 30, 2020, EOG paid cash for property acquisitions of $46 million in the United States. Additionally, during the six months ended June 30, 2020, EOG recognized net gains on asset dispositions of $30 million, primarily due to the sale of proved properties and non-cash property exchanges of unproved leasehold in Texas, New Mexico and the Rocky Mountain area, and received proceeds of approximately $43 million.

EOG Resources, Inc., together with its subsidiaries (collectively, EOG), is one of the largest independent (non-integrated) crude oil and natural gas companies in the United States with proved reserves in the United States and Trinidad. EOG operates under a consistent business and operational strategy that focuses predominantly on maximizing the rate of return on investment of capital by controlling operating and capital costs and maximizing reserve recoveries. Pursuant to this strategy, each prospective drilling location is evaluated by its estimated rate of return. This strategy is intended to enhance the generation of cash flow and earnings from each unit of production on a cost-effective basis, allowing EOG to deliver long-term growth in shareholder value and maintain a strong balance sheet. EOG implements its strategy primarily by emphasizing the drilling of internally generated prospects in order to find and develop low-cost reserves. Maintaining the lowest possible operating cost structure, coupled with efficient and safe operations and robust environmental stewardship practices and performance, is integral in the implementation of EOG's strategy.

Recent Developments. The COVID-19 pandemic and the measures taken to address and limit the spread of the virus adversely affected the economies and financial markets of the world, resulting in an economic downturn beginning in early 2020 that negatively impacted global demand and prices for crude oil and condensate, natural gas liquids (NGLs) and natural gas. The effects of COVID-19 mitigation efforts, including the wide availability of vaccines, tempered by new developments such as emerging COVID-19 variant strains, have resulted in overall increased demand for crude oil and condensate. See ITEM 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed on February 25, 2021 (Annual Report), for further discussion.

In early 2021, the members of the Organization of Petroleum Exporting Countries and Russia (OPEC+) met and agreed to taper off certain of their production curtailments (agreed to in April 2020) through March 2021. In subsequent meetings, OPEC+ indicated it would continue to ease production curtailments, incrementally adding supply (i) as the overall intensity of the COVID-19 pandemic subsides and containment measures are scaled back and (ii) in response to expected increases in demand for crude oil production in the second half of 2021. OPEC+ indicated that it would return to its pre-pandemic production levels by mid-to late-2022.

The continuing rebalancing of crude oil demand and supply resulting from improving or stabilizing conditions in certain economies and financial markets of the world, combined with continuing actions taken by OPEC+, have had a positive impact on crude oil prices in the first six months of 2021. Prices for crude oil and condensate and NGLs returned to pre-pandemic levels in the first quarter of 2021, while natural gas prices recovered at the beginning of 2021.

We will continue to monitor and assess the COVID-19 pandemic and its effect on crude oil demand, the actions of OPEC+ and their effect on crude oil supply, as well as any executive orders or legislative or regulatory actions that could impact the oil and gas industry, to determine the impact on our business and operations, and take appropriate actions where necessary. For related discussion, see ITEM 1, Business – Regulation, ITEM 1A, Risk Factors and ITEM 7, Management's Discussion and Analysis of Financial Condition and Results of Operations - Overview, of our Annual Report.

Commodity Prices. Prices for crude oil and condensate, NGLs and natural gas have historically been volatile. This volatility is expected to continue due to the many uncertainties associated with the world political and economic environment and the global supply of, and demand for, crude oil, NGLs and natural gas and the availability of other energy supplies, the relative competitive relationships of the various energy sources in the view of consumers and other factors.

The market prices of crude oil and condensate, NGLs and natural gas impact the amount of cash generated from EOG's operating activities, which, in turn, impact EOG's financial position and results of operations.

For the first six months of 2021, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and natural gas prices were $61.95 per barrel and $2.76 per million British thermal units (MMBtu), respectively, representing increases of 68% and 49%, respectively, from the average NYMEX prices for the same period in 2020. Market prices for NGLs are influenced by the components extracted, including ethane, propane and butane and natural gasoline, among others, and the respective market pricing for each component. In February 2021, EOG realized higher-than-average daily prices on certain days for deliveries of natural gas volumes due to disruptions throughout the United States from Winter Storm Uri.

United States. EOG's efforts to identify plays with large reserve potential have proven to be successful. EOG continues to drill numerous wells in large acreage plays, which in the aggregate have contributed substantially to, and are expected to continue to contribute substantially to, EOG's crude oil and condensate, NGLs and natural gas production. EOG has placed an emphasis on applying its horizontal drilling and completion expertise to unconventional crude oil and, to a lesser extent, liquids-rich natural gas plays.

During the first six months of 2021, EOG continued to focus on increasing drilling, completion and operating efficiencies gained in prior years. Such efficiencies, combined with new innovation, resulted in lower drilling and completion costs. Winter Storm Uri negatively impacted Lease and Well, Transportation and Gathering and Processing Costs in the first quarter of 2021. In addition, EOG continued to evaluate certain potential crude oil and condensate, NGLs and natural gas exploration and development prospects and to look for opportunities to add drilling inventory through leasehold acquisitions, farm-ins, exchanges or tactical acquisitions. On a volumetric basis, as calculated using the ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas, crude oil and condensate and NGLs production accounted for approximately 75% and 76% of EOG's United States production during the first six months of  2021 and 2020, respectively. During the first six months of 2021, EOG's drilling and completion activities occurred primarily in the Delaware Basin play, Eagle Ford play and Rocky Mountain area. EOG's major producing areas in the United States are in New Mexico and Texas. EOG faced interruptions to sales in certain markets due to disruptions throughout the United States from Winter Storm Uri in the first quarter of 2021.

Trinidad. In Trinidad, EOG continues to deliver natural gas under existing supply contracts. Several fields in the South East Coast Consortium Block, Modified U(a) Block, Block 4(a), Modified U(b) Block, the Banyan Field and the Sercan Area have been developed and are producing natural gas which is sold to the National Gas Company of Trinidad and Tobago Limited and its subsidiary, and crude oil and condensate which is sold to Heritage Petroleum Company Limited (Heritage).

In March 2021, EOG signed a farmout agreement with Heritage, which allows EOG to earn a 65% working interest in a portion of the contract area (EOG Area) governed by the Trinidad Northern Area License. The EOG Area is located offshore the southwest coast of Trinidad. EOG is currently planning and preparing to drill one net exploratory well in the second half of 2021. EOG continues to make progress on the design and fabrication of a platform and related facilities for its previously-announced discovery in the Modified U(a) Block.

Other International. In the Sultanate of Oman, a Royal Decree was issued on March 9, 2021, and EOG became a participant in the Exploration and Production Sharing Agreement for Block 49, holding a 50% working interest. EOG's partner in Block 49 completed the drilling and testing of one gross exploratory well. The results are currently being evaluated. EOG expects to drill two net exploratory wells in Block 36 in the second half of 2021.

In Australia, on April 22, 2021, a subsidiary of EOG entered into a purchase and sale agreement to acquire a 100% interest in the WA-488-P Block, located offshore Western Australia. The purchase and sale agreement is subject to customary closing conditions and is expected to close in the second half of 2021.

In the Sichuan Basin, Sichuan Province, China, EOG worked with its partner, PetroChina, under a production sharing contract and other related agreements, to ensure uninterrupted production. All natural gas produced from the Baijaochang Field was sold under a long-term contract to PetroChina.

In May 2021, EOG closed the sale of its subsidiary which held all of its assets in China. Net production was approximately 25 million cubic feet per day (MMcfd) of natural gas. EOG no longer has any operations or assets in China.

EOG continues to evaluate other select crude oil and natural gas opportunities outside the United States, primarily by pursuing exploitation opportunities in countries where indigenous crude oil and natural gas reserves have been identified.

2021 Capital and Operating Plan. Total anticipated 2021 capital expenditures are estimated to range from approximately $3.7 billion to $4.1 billion, including facilities and gathering, processing and other expenditures, and excluding acquisitions and non-cash transactions. EOG plans to continue to focus a substantial portion of its exploration and development expenditures in its major producing areas in the United States. In particular, EOG will be focused on United States crude oil drilling activity in its Delaware Basin play, Eagle Ford play and Rocky Mountain area where it generates its highest rates-of-return. To further enhance the economics of these plays, EOG expects to continue to improve well performance and lower drilling and completion costs through efficiency gains, new innovation and initiatives to manage procurement and service costs. In addition, EOG expects to spend a portion of its anticipated 2021 capital expenditures on leasing acreage and evaluating new prospects.

In 2021, total crude oil production is expected to remain at fourth quarter 2020 levels. Further, EOG expects to continue to focus on reducing operating costs in 2021 through efficiency improvements.

Management continues to believe EOG has one of the strongest prospect inventories in EOG's history. When it fits EOG's strategy, EOG will make acquisitions that bolster existing drilling programs or offer incremental exploration and/or production opportunities.

Capital Structure. One of management's key strategies is to maintain a strong balance sheet with a consistently below average debt-to-total capitalization ratio as compared to those in EOG's peer group. EOG's debt-to-total capitalization ratio was 20% at June 30, 2021 and 22% at December 31, 2020. As used in this calculation, total capitalization represents the sum of total current and long-term debt and total stockholders' equity.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

At June 30, 2021, EOG maintained a strong financial and liquidity position, including $3.9 billion of cash and cash equivalents on hand and $2.0 billion of availability under its senior unsecured revolving credit facility.

EOG has significant flexibility with respect to financing alternatives, including borrowings under its commercial paper program, bank borrowings, borrowings under its senior unsecured revolving credit facility, joint development agreements and similar agreements and equity and debt offerings.

Wellhead crude oil and condensate revenues for the second quarter of 2021 increased $2,084 million, or 339%, to $2,699 million from $615 million for the same period of 2020. The increase was due to a higher composite average price ($1,866 million) and an increase of 118 MBbld, or 35%, in wellhead crude oil and condensate production ($218 million). Increased production was primarily due to increases in the Permian Basin, the Rocky Mountain area and the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the second quarter of 2021 increased 224% to $66.12 per barrel compared to $20.40 per barrel for the same period of 2020.

NGL revenues for the second quarter of 2021 increased $274 million, or 295%, to $367 million from $93 million for the same period of 2020 due to a higher composite average price ($239 million) and an increase of 37 MBbld, or 37%, in NGL deliveries ($35 million). Increased production was primarily due to increases in the Permian Basin and the Rocky Mountain area. EOG's composite NGL price for the second quarter of 2021 increased 186% to $29.15 per barrel compared to $10.20 per barrel for the same period of 2020.

Wellhead natural gas revenues for the second quarter of 2021 increased $263 million, or 187%, to $404 million from $141 million for the same period of 2020. The increase was due to a higher average composite price ($227 million) and an increase in natural gas deliveries ($36 million). Natural gas deliveries for the second quarter of 2021 increased 298 MMcfd, or 26%, compared to the same period of 2020 due primarily to increased production of associated natural gas from the Permian Basin and higher natural gas volumes in the Rocky Mountain area and Trinidad, partially offset by lower natural gas volumes associated with the disposition of the Marcellus Shale assets in the third quarter of 2020 and lower deliveries in South Texas. EOG's composite wellhead natural gas price for the second quarter of 2021 increased 126% to $3.07 per Mcf compared to $1.36 per Mcf for the same period of 2020.

During the second quarter of 2021, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $427 million compared to net losses of $127 million for the same period of 2020. During the second quarter of 2021, net cash paid for settlements of financial commodity derivative contracts was $193 million compared to net cash received from settlements of financial commodity derivative contracts of $640 million for the same period of 2020.

Gathering, processing and marketing revenues are revenues generated from sales of third-party crude oil, NGLs and natural gas, as well as fees associated with gathering third-party natural gas and revenues from sales of EOG-owned sand. Purchases and sales of third-party crude oil and natural gas may be utilized in order to balance firm transportation capacity with production in certain areas and to utilize excess capacity at EOG-owned facilities. EOG sells sand in order to balance the timing of firm purchase agreements with completion operations and to utilize excess capacity at EOG-owned facilities. Marketing costs represent the costs to purchase third-party crude oil, natural gas and sand and the associated transportation costs, as well as costs associated with EOG-owned sand sold to third parties.

Gathering, processing and marketing revenues less marketing costs for the second quarter of 2021 increased $113 million as compared to the same period of 2020 primarily due to higher margins on crude oil marketing activities. The margin on crude oil marketing activities for the second quarter of 2020 was negatively impacted by EOG's decision early in the second quarter of 2020 to reduce commodity price volatility by selling May and June 2020 deliveries under fixed price arrangements.

Operating and Other Expenses.  For the second quarter of 2021, operating expenses of $2,968 million were $778 million higher than the $2,190 million incurred during the second quarter of 2020.  The following table presents the costs per barrel of oil equivalent (Boe) for the three-month periods ended June 30, 2021 and 2020:

	Three Months Ended June 30,
	2021		2020
Lease and Well	$	3.58	$	4.32
Transportation Costs	2.84		2.67
Gathering and Processing Costs	1.70		1.71
Depreciation, Depletion and Amortization (DD&A) -
Oil and Gas Properties	11.63		11.84
Other Property, Plant and Equipment	0.50		0.62
General and Administrative (G&A)	1.59		2.32
Interest Expense, Net	0.60		0.96
Total (1)	$	22.44	$	24.44

(1)Total excludes exploration costs, dry hole costs, impairments, marketing costs and taxes other than income.

The primary factors impacting the cost components of per-unit rates of lease and well, transportation costs, gathering and processing costs, DD&A, G&A and net interest expense for the three months ended June 30, 2021, compared to the same period of 2020, are set forth below. See "Operating Revenues and Other" above for a discussion of wellhead volumes.

Lease and well expenses include expenses for EOG-operated properties, as well as expenses billed to EOG from other operators where EOG is not the operator of a property. Lease and well expenses can be divided into the following categories: costs to operate and maintain crude oil and natural gas wells, the cost of workovers and lease and well administrative expenses. Operating and maintenance costs include, among other things, pumping services, salt water disposal, equipment repair and maintenance, compression expense, lease upkeep and fuel and power. Workovers are operations to restore or maintain production from existing wells.

Each of these categories of costs individually fluctuates from time to time as EOG attempts to maintain and increase production while maintaining efficient, safe and environmentally responsible operations. EOG continues to increase its operating activities by drilling new wells in existing and new areas. Operating and maintenance costs within these existing and new areas, as well as the costs of services charged to EOG by vendors, fluctuate over time.

Lease and well expenses of $270 million for the second quarter of 2021 increased $25 million from $245 million for the same prior year period primarily due to increased workover expenditures ($18 million) and increased operating and maintenance costs ($8 million), both in the United States. Lease and well expenses increased in the United States primarily due to increased operating activities resulting in increased production.

Transportation costs represent costs associated with the delivery of hydrocarbon products from the lease or an aggregation point on EOG's gathering system to a downstream point of sale. Transportation costs include transportation fees, storage and terminal fees, the cost of compression (the cost of compressing natural gas to meet pipeline pressure requirements), the cost of dehydration (the cost associated with removing water from natural gas to meet pipeline requirements), gathering fees and fuel costs.

Transportation costs of $214 million for the second quarter of 2021 increased $62 million from $152 million for the same prior year period primarily due to increased transportation costs related to production from the Permian Basin ($52 million) and the Rocky Mountain area ($9 million).

Gathering and processing costs represent operating and maintenance expenses and administrative expenses associated with operating EOG's gathering and processing assets as well as natural gas processing fees and certain NGL fractionation fees paid to third parties. EOG pays third parties to process the majority of its natural gas production to extract NGLs.

-27-

Gathering and processing costs increased $31 million to $128 million for the second quarter of 2021 compared to $97 million for the same prior year period primarily due to increased gathering and processing fees related to production from the Permian Basin ($14 million), the Rocky Mountain area ($8 million) and the Eagle Ford ($4 million).

DD&A of the cost of proved oil and gas properties is calculated using the unit-of-production method. EOG's DD&A rate and expense are the composite of numerous individual DD&A group calculations. There are several factors that can impact EOG's composite DD&A rate and expense, such as field production profiles, drilling or acquisition of new wells, disposition of existing wells and reserve revisions (upward or downward) primarily related to well performance, economic factors and impairments. Changes to these factors may cause EOG's composite DD&A rate and expense to fluctuate from period to period. DD&A of the cost of other property, plant and equipment is generally calculated using the straight-line depreciation method over the useful lives of the assets.

DD&A expenses for the second quarter of 2021 increased $207 million to $914 million from $707 million for the same prior year period. DD&A expenses associated with oil and gas properties for the second quarter of 2021 were $205 million higher than the same prior year period. The increase primarily reflects increased production in the United States ($215 million) and in Trinidad ($5 million) and higher unit rates in Trinidad ($8 million); partially offset by lower unit rates in the United States ($20 million). Unit rates in the United States decreased primarily due to reserves added at lower costs as a result of increased efficiencies.

G&A expenses of $120 million for the second quarter of 2021 decreased $12 million from $132 million for the same prior year period primarily due to decreased idle equipment and termination fees ($26 million), partially offset by increased employee-related costs ($5 million) and professional and legal services ($3 million).

Interest expense, net of $45 million for the second quarter of 2021 decreased $9 million compared to the same prior year period primarily due to repayment in February 2021 of the $750 million aggregate principal amount of 4.100% Senior Notes due 2021 ($8 million) and repayment in June 2020 of the $500 million aggregate principal amount of 4.40% Senior Notes due 2020 ($4 million).

Exploration costs of $35 million for the second quarter of 2021 increased $8 million from $27 million for the same prior year period due primarily to increased geological and geophysical expenditures in the United States.

Impairments include: amortization of unproved oil and gas property costs as well as impairments of proved oil and gas properties; other property, plant and equipment; and other assets. Unproved properties with acquisition costs that are not individually significant are aggregated, and the portion of such costs estimated to be nonproductive is amortized over the remaining lease term. Unproved properties with individually significant acquisition costs are reviewed individually for impairment. When circumstances indicate that a proved property may be impaired, EOG compares expected undiscounted future cash flows at a DD&A group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimates of (and assumptions regarding) future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated by using the Income Approach described in the Fair Value Measurement Topic of the Financial Accounting Standards Board's Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

-28-

The following table represents impairments for the second quarter of 2021 and 2020 (in millions):

	Three Months Ended June 30,
	2021		2020
Proved properties	$	—	$	26
Unproved properties	43		60
Other assets	—		219
Firm commitment contracts	1		—
Total	$	44	$	305

Impairments of other property, plant and equipment in the second quarter of 2020 were primarily related to the write-down to fair value of sand and crude-by-rail assets in the United States.

Taxes other than income include severance/production taxes, ad valorem/property taxes, payroll taxes, franchise taxes and other miscellaneous taxes. Severance/production taxes are generally determined based on wellhead revenues, and ad valorem/property taxes are generally determined based on the valuation of the underlying assets.

Taxes other than income for the second quarter of 2021 increased $158 million to $239 million (6.9% of wellhead revenues) from $81 million (9.4% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased severance/production taxes in the United States.

EOG recognized an income tax provision of $217 million for the second quarter of 2021 compared to an income tax benefit of $235 million for the second quarter of 2020, primarily due to increased pretax income.  The net effective tax rate for the second quarter of 2021 decreased to 19% from 21% for the second quarter of 2020, mostly due to certain tax benefits related to EOG's exiting of its Canadian operations.

Six Months Ended June 30, 2021 vs. Six Months Ended June 30, 2020

Operating Revenues. During the first six months of 2021, operating revenues increased $2,012 million, or 35%, to $7,833 million from $5,821 million for the same period of 2020. Total wellhead revenues for the first six months of 2021 increased $3,375 million, or 103%, to $6,660 million from $3,285 million for the same period of 2020. During the first six months of 2021, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $794 million compared to net gains of $1,079 million for the same period of 2020. Gathering, processing and marketing revenues for the first six months of 2021 increased $469 million, or 33%, to $1,870 million from $1,401 million for the same period of 2020. Net gains on asset dispositions were $45 million for the first six months of 2021 compared to net gains of $30 million for the same period of 2020.

Wellhead crude oil and condensate revenues for the first six months of 2021 increased $2,270 million, or 85%, to $4,950 million from $2,680 million for the same period of 2020 due to a higher composite average price ($2,071 million) and an increase of 33 MBbld, or 8%, in wellhead crude oil and condensate production ($199 million). Increased production was primarily due to increases in the Permian Basin and the Rocky Mountain area, partially offset by decreased production in the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the first six months of 2021 increased 72% to $62.18 per barrel compared to $36.16 per barrel for the same period of 2020.

NGL revenues for the first six months of 2021 increased $427 million, or 168%, to $681 million from $254 million for the same period of 2020 due to a higher composite average price. EOG's composite NGL price for the first six months of 2021 increased 169% to $28.62 per barrel compared to $10.65 per barrel for the same period of 2020.

Wellhead natural gas revenues for the first six months of 2021 increased $678 million, or 193%, to $1,029 million from $351 million for the same period of 2020. The increase was due to a higher composite wellhead natural gas price ($644 million) and an increase in natural gas deliveries ($34 million). Natural gas deliveries for the first six months of 2021 increased 132 MMcfd, or 10%, compared to the same period of 2020 due primarily to increased production of associated natural gas from the Permian Basin and higher natural gas volumes in Trinidad and the Rocky Mountain area, partially offset by lower natural gas volumes associated with the disposition of the Marcellus Shale assets in the third quarter of 2020 and lower deliveries in South Texas. EOG's composite wellhead natural gas price for the first six months of 2021 increased 167% to $4.08 per Mcf compared to $1.53 per Mcf for the same period of 2020.

During the first six months of 2021, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $794 million compared to net gains of $1,079 million for the same period of 2020. During the first six months of 2021, net cash paid for settlements of financial commodity derivative contracts was $223 million compared to net cash received from settlements of financial commodity derivative contracts of $724 million for the same period of 2020.

Gathering, processing and marketing revenues less marketing costs for the first six months of 2021 increased $194 million as compared to the same period of 2020 primarily due to higher margins on crude oil marketing activities, partially offset by lower margins on natural gas marketing activities. The margin on crude oil marketing activities for the first six months of 2020 was negatively impacted by the price decline for crude oil in inventory awaiting delivery to customers and EOG's decision early in the second quarter of 2020 to reduce commodity price volatility by selling May and June 2020 deliveries under fixed price arrangements.

Operating and Other Expenses. For the first six months of 2021, operating expenses of $5,730 million were $1,120 million lower than the $6,850 million incurred during the same period of 2020. The following table presents the costs per Boe for the six-month periods ended June 30, 2021 and 2020:

	Six Months Ended June 30,
	2021		2020
Lease and Well	$	3.71	$	4.22
Transportation Costs	2.86		2.64
Gathering and Processing Costs	1.84		1.65
DD&A -
Oil and Gas Properties	11.96		12.03
Other Property, Plant and Equipment	0.51		0.49
G&A	1.58		1.81
Interest Expense, Net	0.63		0.73
Total (1)	$	23.09	$	23.57

(1)Total excludes exploration costs, dry hole costs, impairments, marketing costs and taxes other than income.

The primary factors impacting the cost components of per-unit rates of lease and well, transportation costs, gathering and processing costs, DD&A, G&A and net interest expense for the six months ended June 30, 2021, compared to the same period of 2020 are set forth below. See "Operating Revenues" above for a discussion of wellhead volumes.

-31-

Lease and well expenses of $540 million for the first six months of 2021 decreased $35 million from $575 million for the same prior year period primarily due to decreased operating and maintenance costs in the United States ($22 million) and Canada ($5 million) and decreased lease and well administrative expenses in the United States ($8 million).

Transportation costs of $416 million for the first six months of 2021 increased $56 million from $360 million for the same prior year period primarily due to increased transportation costs related to production from the Permian Basin ($62 million) and the Rocky Mountain area ($7 million), partially offset by decreased transportation costs related to production from the Eagle Ford ($10 million).

Gathering and processing costs of $267 million for the first six months of 2021 increased $42 million compared to the same prior year period primarily due to increased gathering and processing fees related to production from the Permian Basin ($17 million) and the Rocky Mountain area ($10 million) and increased operating and maintenance expenses related to production from the Rocky Mountain area ($5 million) and the Permian Basin ($5 million).

DD&A expenses for the first six months of 2021 increased $107 million to $1,814 million from $1,707 million for the same prior year period. DD&A expenses associated with oil and gas properties for the first six months of 2021 were $99 million higher than the same prior year period. The increase primarily reflects increased production in the United States ($102 million) and in Trinidad ($7 million) and higher unit rates in Trinidad ($10 million), partially offset by lower unit rates in the United States ($16 million). Unit rates in the United States decreased primarily due to reserves added at lower costs as a result of increased efficiencies. DD&A expenses associated with other property, plant and equipment for the first six months of 2021 were $8 million higher than the same prior year period primarily due to an increase in expense related to storage assets.

G&A expenses of $230 million for the first six months of 2021 decreased $16 million from $246 million for the same prior year period primarily due to decreased idle equipment and termination fees.

Interest expense, net of $92 million for the first six months of 2021 decreased $7 million compared to the same prior year period primarily due to repayment in February 2021 of the $750 million aggregate principal amount of 4.100% Senior Notes due 2021 ($13 million), repayment in June 2020 of the $500 million aggregate principal amount of 4.40% Senior Notes due 2020 ($9 million) and repayment in April 2020 of the $500 million aggregate principal amount of 2.45% Senior Notes due 2020 ($3 million), partially offset by the issuance in April 2020 of the $750 million aggregate principal amount of 4.950% Senior Notes due 2050 ($11 million) and issuance in April 2020 of the $750 million aggregate principal amount of 4.375% Senior Notes due 2030 ($10 million).

The following table represents impairments for the six-month periods ended June 30, 2021 and 2020 (in millions):

	Six Months Ended June 30,
	2021		2020
Proved properties	$	—	$	1,411
Unproved properties	86		117
Other assets	—		290
Firm commitment contracts	2		60
Total	$	88	$	1,878

Impairments of proved properties in the first six months of 2020 were primarily due to the decline in commodity prices and were primarily related to the write-down to fair value of legacy and non-core natural gas, crude oil and combo plays in the United States. Impairments of other assets in the first six months of 2020 were primarily for the write-down to fair value of sand and crude-by-rail assets and a commodity price-related write-down of other assets. Impairments of firm commitment contracts in the first six months of 2020 were a result of the decision to exit the Horn River Basin in Canada.

-32-

Taxes other than income for the first six months of 2021 increased $216 million to $454 million (6.8% of wellhead revenues) from $238 million (7.2% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased severance/production taxes ($205 million) and decreased state severance tax refunds ($12 million), all in the United States.

Other income (expense), net for the first six months of 2021 increased $20 million compared to the same prior year period primarily due to an increase in deferred compensation expense ($18 million) and decreased interest income ($7 million), partially offset by higher equity income from ammonia plants in Trinidad ($5 million).

EOG recognized an income tax provision of $421 million for the first six months of 2021 compared to an income tax benefit of $214 million for the first six months of 2020, primarily due to increased pretax income. The net effective tax rate for the first six months of 2021 increased to 21% from 19% in the first six months of 2020. The higher effective tax rate is mostly due to taxes attributable to EOG's foreign operations.

-33-

Capital Resources and Liquidity

Cash Flow. The primary sources of cash for EOG during the six months ended June 30, 2021, were funds generated from operations and proceeds from sales of assets. The primary uses of cash were funds used in operations; exploration and development expenditures; long-term debt repayments; dividend payments to stockholders; net cash paid for settlements of commodity derivative contracts and other property, plant and equipment expenditures. During the first six months of 2021, EOG's cash balance increased $551 million to $3,880 million from $3,329 million at December 31, 2020.

Net cash provided by operating activities of $3,429 million for the first six months of 2021 increased $756 million compared to the same period of 2020 primarily due to an increase in wellhead revenues ($3,375 million) and an increase in gathering, processing and marketing revenues less marketing costs ($194 million), partially offset by net cash used in working capital in the first six months of 2021 ($621 million) compared to net cash provided by working capital in the first six months of 2020 ($552 million), an increase in net cash paid for settlements of financial commodity derivative contracts ($947 million), an unfavorable change in net cash paid for income taxes ($583 million) and an increase in cash operating expenses ($265 million).

Net cash used in investing activities of $1,649 million for the first six months of 2021 decreased $727 million compared to the same period of 2020 due to net cash provided by working capital associated with investing activities in the first six months of 2021 ($145 million) compared to net cash used in working capital associated with investing activities in the first six months of 2020 ($282 million), a decrease in additions to oil and gas properties ($147 million), an increase in proceeds from the sale of assets ($103 million) and a decrease in additions to other property, plant and equipment ($50 million).

Net cash used in financing activities of $1,229 million for the first six months of 2021 included repayments of long-term debt ($750 million), cash dividend payments ($458 million) and repayment of finance lease liabilities ($18 million). Net cash provided by financing activities of $92 million for the first six months of 2020 included net proceeds from the issuance of long-term debt ($1,484 million). Net cash used in financing activities for the first six months of 2020 included repayments of long-term debt ($1,000 million) and cash dividend payments ($384 million).

-34-

Total Expenditures. For the year 2021, EOG's updated budget for exploration and development and other property, plant and equipment expenditures is estimated to range from approximately $3.7 billion to $4.1 billion, excluding acquisitions and non-cash transactions. The table below sets out components of total expenditures for the six-month periods ended June 30, 2021 and 2020 (in millions):

	Six Months Ended June 30,
	2021		2020
Expenditure Category
Capital
Exploration and Development Drilling	$	1,444	$	1,694
Facilities	187		210
Leasehold Acquisitions (1)	104		75
Property Acquisitions (2)	95		51
Capitalized Interest	15		17
Subtotal	1,845		2,047
Exploration Costs	68		67
Dry Hole Costs	24		—
Exploration and Development Expenditures	1,937		2,114
Asset Retirement Costs	48		25
Total Exploration and Development Expenditures	1,985		2,139
Other Property, Plant and Equipment (3)	171		221
Total Expenditures	$	2,156	$	2,360

(1)    Leasehold acquisitions included $22 million and $48 million for the six-month periods ended June 30, 2021 and 2020, respectively, related to non-cash property exchanges.

(2)    Property acquisitions included $3 million and $7 million for the six-month periods ended June 30, 2021 and 2020, respectively, related to non-cash property exchanges.

(3)    Other property, plant and equipment included $74 million and $73 million of non-cash additions for the six-month periods ended June 30, 2021 and 2020, respectively, primarily related to finance lease transactions for storage facilities.

Exploration and development expenditures of $1,937 million for the first six months of 2021 were $177 million lower than the same period of 2020 primarily due to decreased exploration and development drilling expenditures in the United States ($242 million) and Trinidad ($16 million) and decreased facilities expenditures ($23 million), partially offset by increased property acquisitions ($44 million), increased leasehold acquisitions ($29 million) and increased exploration and development expenditures in Other International ($8 million). Exploration and development expenditures for the first six months of 2021 of $1,937 million consisted of $1,630 million in development drilling and facilities, $197 million in exploration, $95 million in property acquisitions and $15 million in capitalized interest. Exploration and development expenditures for the first six months of 2020 of $2,114 million consisted of $1,840 million in development drilling and facilities, $206 million in exploration, $51 million in property acquisitions and $17 million in capitalized interest.

The level of exploration and development expenditures, including acquisitions, will vary in future periods depending on energy market conditions and other economic factors. EOG believes it has significant flexibility and availability with respect to financing alternatives and the ability to adjust its exploration and development expenditure budget as circumstances warrant. While EOG has certain continuing commitments associated with expenditure plans related to its operations, such commitments are not expected to be material when considered in relation to the total financial capacity of EOG.

Commodity Derivative Transactions. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method. Under this accounting method, changes in the fair value of outstanding financial instruments are recognized as gains or losses in the period of change and are recorded as Gains (Losses) on Mark-to-Market Commodity Derivative Contracts on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss). The related cash flow impact is reflected in Cash Flows from Operating Activities on the Condensed Consolidated Statements of Cash Flows.

The total fair value of EOG's commodity derivative contracts was reflected on the Condensed Consolidated Balance Sheets at June 30, 2021, as a net liability of $410 million.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of July 30, 2021. Crude oil and NGL volumes are presented in MBbld and prices are presented in $/Bbl. Natural gas volumes are presented in MMBtu per day (MMBtud) and prices are presented in dollars per MMBtu ($/MMBtu).

EXHIBIT 10.2

CHANGE OF CONTROL AGREEMENT

This Change of Control Agreement (“Agreement”) between EOG Resources, Inc., a Delaware corporation (the “Company”), and Jeffrey R. Leitzell (the “Employee”) is effective as of this 17th day of June, 2021 (the “Effective Date”). Certain capitalized terms used herein are defined in Section 21.

WITNESSETH:

Whereas, the Company considers it to be in the best interests of its stockholders to encourage the continued employment of certain key employees of the Company notwithstanding the possibility, threat or occurrence of a Change of Control of the Company; and

Whereas, the Employee is a key employee of the Company; and

Whereas, the Company believes that the possibility of the occurrence of a Change of Control of the Company may result in the termination by the Employee of the Employee’s employment by the Company or in the distraction of the Employee from the performance of Employee’s duties to the Company, in either case to the detriment of the Company and its stockholders; and

Whereas, the Company recognizes that the Employee could suffer adverse financial and professional consequences if a Change of Control of the Company were to occur; and

Whereas, the Company wishes to continue to protect the Employee if a Change of Control of the Company occurs, thereby encouraging the Employee to remain in the employ of the Company and not to be distracted from the performance of Employee’s duties to the Company by the possibility of a Change of Control of the Company; and

Now, Therefore, the parties agree as follows:

SECTION 1.        OTHER EMPLOYMENT ARRANGEMENTS.

(a)    This Agreement does not affect the Employee’s existing or future employment arrangements with the Company unless a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement. The Employee’s employment with the Company shall continue to be governed by the Employee’s existing or future employment agreements with the Company, if any, or, in the absence of any employment agreement, shall continue to be at the will of the Company, except that if a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement and the Employee’s employment with the Company is terminated (whether by the Employee or the Company or automatically as provided in Section 3) after the occurrence of that Change of Control of the Company, then the Employee shall be entitled to receive certain benefits as provided in this Agreement.

(b)    Nothing in this Agreement shall prevent or limit the Employee’s continuing or future participation in any plan, program, policy or practice of or provided by the Company or any of its Affiliates and for which the Employee may qualify, nor shall anything herein limit or otherwise affect such rights as the Employee may have under any contract or agreement with the Company or any of its Affiliates. Amounts which are vested benefits or which the Employee is otherwise entitled to receive under any plan, program, policy or practice of or provided by, or any contract or agreement with, the Company or any of its Affiliates at or subsequent to the date of termination of the Employee’s employment with the Company shall be payable or otherwise provided in accordance with such plan, program, policy or practice or contract or agreement except as explicitly modified by this Agreement.

SECTION 2.    CHANGE OF CONTROL OF THE COMPANY.

    A “Change of Control of the Company” shall mean the occurrence of any of the following events:

(a)    The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (an “Exchange Act Person”) of beneficial ownership (within the meaning of Rule 13d3 promulgated under the Exchange Act) of 20% or more of either the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or the combined voting power of the then-outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that, for purposes of this clause (a), the following acquisitions shall not constitute a Change of Control of the Company: (i) any acquisition directly from the Company, (ii) any acquisition by the Company, (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any Affiliated Company, (iv) any acquisition by any corporation pursuant to a transaction that complies with subclauses (i), (ii) and (iii) of clause (c) of this Section 2 or (v) an acquisition by a Qualified Institutional Investor, but only for so long as such investor remains a Qualified Institutional Investor;

(b)    Individuals who, as of May 3, 2005, constitute the Board of Directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board of Directors; provided, however, that any individual becoming a director subsequent to May 3, 2005, whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of an Exchange Act Person other than the Board of Directors;

2

(c)    Consummation of a reorganization, merger, consolidation or sale or other disposition of all or substantially all of the assets of the Company or the acquisition of the assets or stock of another entity (a “Business Combination”), in each case, unless, following such Business Combination, (i) all or substantially all of the individuals and entities that were the beneficial owners of the Outstanding Company Common Stock and the Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 60% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation that, as a result of such transaction, owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately prior to such Business Combination of the Outstanding Company Common Stock and the Outstanding Company Voting Securities, as the case may be, (ii) no Exchange Act Person (excluding any corporation resulting from such Business Combination or any employee benefit plan (or related trust) of the Company or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20% or more of, respectively, the then-outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the then-outstanding voting securities of such corporation, except to the extent that such ownership existed prior to the Business Combination, and (iii) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement or of the action of the Board of Directors providing for such Business Combination; or

(d)Approval by the stockholdersof the Company of a complete liquidation or dissolution of the Company.

Notwithstanding anything contained in this Agreement to the contrary, if (i) the Employee’s employment with the Company is terminated, or (ii) an event occurs which, had it occurred after a Change of Control of the Company, would with proper notice from Employee constitute an Event of Termination for Good Reason, and if it is reasonably demonstrated by the Employee that such action (A) was taken at the request of a third party that has taken steps reasonably calculated to effect a Change of Control of the Company or (B) otherwise arose in connection with or anticipation of a Change of Control of the Company, then for all purposes of this Agreement, such Change of Control of the Company shall be deemed to have occurred on the date immediately prior to the date of such termination or event.

SECTION 3.        TERM OF THIS AGREEMENT.

The term of this Agreement shall begin on the Effective Date and shall expire on the first to occur of:

3

(a)    the Employee’s death, the Employee’s Disability or the Employee’s Retirement, which events shall also be deemed automatically to terminate the Employee’s employment by the Company; or

(b)    the termination by the Employee or the Company of the Employee’s employment by the Company.

The expiration of the term of this Agreement shall not terminate this Agreement itself or affect the right of the Employee or the Employee’s legal representatives to enforce the payment of any amount or other benefit to which the Employee was entitled before the expiration of the term of this Agreement or to which the Employee became entitled as a result of the event that caused the term of this Agreement to expire.

SECTION 4.        EVENT OF TERMINATION FOR CAUSE.

(a)An “Event of Termination for Cause” shall mean the Employee's (i) conviction of a felony involving moral turpitude (which, through lapse of time or otherwise, is not subject to appeal), (ii) willful refusal without proper legal cause to perform employee's duties and responsibilities which remains uncorrected for thirty (30) daysfollowing written notice to the Employee by the Company of such event, or (iii) willfully engaging in conduct which the Employee has, or reasonably should have, reason to know is materially injurious to the Company.

(b)For purposes of this Section 4, no act, or failure to act, on the part of the Employee shall be considered “willful” unless it is done, or omitted to be done, by the Employee in bad faith or without reasonable belief that the Employee’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board of Directors or upon the instructions of the Chief Executive Officer of the Company or a senior officer of the Company or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Employee in good faith and in the best interests of the Company.

(c)The cessation of employment of the Employee as a result of the alleged occurrence of an event referred to in clause (ii) or (iii) of the definition of “Event of Termination for Cause” shall not be deemed to be as a result of an Event of Termination for Cause unless and until there shall have been delivered to the Employee a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Board of Directors (excluding the Employee, if the Employee is a member of the Board of Directors) at a meeting of the Board of Directors called and held for such purpose (after reasonable notice is provided to the Employee and the Employee is given an opportunity, together with counsel for the Employee, to be heard before the Board of Directors), finding that, in the good faith opinion of the Board of Directors, the Employee is guilty of the conduct described in clause (ii) or (iii) of such definition and specifying the particulars thereof in detail. Any determination of the Board of Directors under this clause (c) shall not be binding on the Employee, shall not be conclusive

4

as to whether an Event of Termination for Cause has occurred, and shall not affect Employee’s right to contest whether an Event of Termination for Cause has occurred.

SECTION 5.        EVENT OF TERMINATION FOR GOOD REASON.

An “Event of Termination for Good Reason” shall mean, after a Change of Control of the Company, the occurrence of any of the following events, provided Employee serves written notice of termination in connection with or based upon any such event within ninety (90) days of the Employee’s knowledge of the occurrence of such event:

(a)    a reduction in the Employee's authority and/or responsibilities (whether or not occurring solely as a result of the Company’s ceasing to be a publicly traded entity); or

(b)    a reduction in Employee's Annual Base Salary as in effect immediately prior to the Change of Control of the Company or a reduction in Employee’s target annual bonus as in effect immediately prior to the Change of Control of the Company, or the failure to continue the Employee's full participation in any employee benefit plan or program (unless replaced by a substantially comparable plan or program) in which Employee is eligible to participate immediately prior to the Change of Control of the Company (other than as a result of the normal expiration of such plan or program), in each case other than as a part of a general program to reduce compensation or benefits on a proportional basis relative to all other employees of the Company; or

(c)    a relocation of the Employee's primary place of work to a location more than 50 miles away from the Employee's primary place of work immediately prior to the Change of Control of the Company (provided, however, this clause (c) shall no longer apply to an employee after he has accepted any such relocation after a Change of Control of the Company has occurred and the above referenced ninety (90) day period has passed), or

(d)    the failure of the Company to obtain the assumption in writing of its obligation to perform this Agreement by any successor to the Company prior to a merger, consolidation, sale or similar transaction.

For the avoidance of doubt, any action referred to in clause (a), (b), (c) or (d) above shall constitute an Event of Termination for Good Reason under the foregoing definition regardless of whether the Company is permitted to take such action under any employment contract with the Employee.

SECTION 6.    NOTICE OF TERMINATION.

If a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement, any termination by the Employee or the Company of the Employee’s employment by the Company, or any determination of the Employee’s Disability, that occurs within two (2) years of such Change of Control shall be communicated by notice to the other party that shall indicate the specific paragraph of Section 7 pursuant to which the Employee is to

5

receive benefits as a result of the termination. If the notice states that the Employee’s employment by the Company has been automatically terminated as a result of the Employee’s Disability, the notice shall specifically describe the basis for the determination of the Employee’s Disability and shall state the date of the determination of the Employee’s Disability, which date shall be not more than ten (10) days before the date such notice is given. If the notice is from the Company and states that the Employee’s employment by the Company is terminated by the Company as a result of the occurrence of an Event of Termination for Cause, the notice shall specifically describe the action or inaction of the Employee that the Company believes constitutes an Event of Termination for Cause, and in the case of a termination under clause (ii) or (iii) of the definition of Event of Termination for Cause, shall include the resolution of the Board of Directors referred to in Section 4(c). If the notice is from the Employee and states that the Employee’s employment by the Company is terminated by the Employee as a result of the occurrence of an Event of Termination for Good Reason, the notice shall specifically describe the action or inaction of the Company that the Employee believes constitutes an Event of Termination for Good Reason. Each notice given pursuant to this Section 6 (other than a notice stating that the Employee’s employment by the Company has been automatically terminated as a result of the Employee’s Disability) shall state a date, which shall be not fewer than thirty (30) days nor more than sixty (60) days after the date such notice is given, on which the termination of the Employee’s employment by the Company is effective. The date so stated in accordance with this Section 6 shall be the “Termination Date”. If a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement, any subsequent purported termination by the Company of the Employee’s employment by the Company, or any subsequent purported determination by the Company of the Employee’s Disability, within two (2) years of such Change of Control shall be ineffective unless that termination or determination shall have been communicated by the Company to the Employee by notice that meets the requirements of the foregoing provisions of this Section 6 and the provisions of Section 9.

SECTION 7.    BENEFITS PAYABLE ON CHANGE OF CONTROL AND TERMINATION.

    If a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement, and the Employee’s employment by the Company is terminated (whether by the Employee or the Company or automatically as provided in Section 3) within two (2) years after the occurrence of that Change of Control of the Company, the Employee shall be entitled to the following benefits:

(a)    If the Employee’s employment by the Company is terminated by the Company as a result of the occurrence of an Event of Termination for Cause, or by the Employee before the occurrence of an Event of Termination for Good Reason, then the Company shall pay to the Employee the Base Salary accrued through the Termination Date but not previously paid to the Employee, and the Employee shall be entitled to any other amounts or benefits provided under any plan, policy, practice, program, contract or arrangement of or with the Company, which shall be governed by the terms thereof (except as explicitly modified by this Agreement).

6

(b)    If the Employee’s employment by the Company is automatically terminated as a result of the Employee’s death, the Employee’s Disability or the Employee’s Retirement, then the Company shall pay to the Employee the Base Salary accrued through the date of the occurrence of that event but not previously paid to the Employee, and the Employee shall be entitled to any other amounts or benefits provided under any plan, policy, practice, program, contract or arrangement of or with the Company, which shall be governed by the terms thereof (except as explicitly modified by this Agreement).

(c)    If the Employee’s employment by the Company is terminated (x) by the Company, other than as a result of the occurrence of an Event of Termination for Cause, or (y) by the Employee after the occurrence of an Event of Termination for Good Reason, then the Employee shall be entitled to the following:

(i)    the Company shall pay to the Employee the Base Salary and compensation for earned but unused vacation time accrued through the Termination Date but not previously paid to the Employee;

(ii)    the Company shall pay to the Employee, as a lump sum, an amount equal to the total of the following amounts:

(A)    2.99 times the amount of the Employee’s Annual Base Salary as in effect immediately prior to the Change of Control (or if increased, immediately prior to the Termination Date); plus

(B)    two (2) times the amount of the Employee’s target annual bonus as in effect immediately prior to the Change of Control (or if no target annual bonus for the year in which the Change of Control occurs has been set, the target annual bonus for the immediately prior year) (or if increased, immediately prior to the Termination Date); plus

(C)    the amount of the retirement contributions that would have been made by the Company on behalf of the Employee to the Company’s Savings and Retirement Plan (as amended, supplemented, modified and/or restated from time to time, and including any replacement or successor plan) if the Employee had continued to be employed by the Company at the Employee’s Annual Base Salary and target annual bonus as in effect immediately prior to the Change of Control (or if increased, immediately prior to the Termination Date) for three (3) years following the Termination Date; and plus

(D)    the amount of the matching contributions that would have been made by the Company on behalf of the Employee to the Company’s Savings and Retirement Plan (as amended, supplemented, modified and/or restated from time to time, and including any replacement or successor plan) if the Employee had continued to be employed by the Company at the Employee’s Annual Base Salary and target annual bonus as in effect immediately prior to the Change of Control (or if increased, immediately prior to the Termination Date) for three (3) years following the Termination Date and had continued to contribute to the Company’s Savings and Retirement Plan (as amended, supplemented, modified and/or restated from time to time, and

7

including any replacement or successor plan) during such three (3) year period at the Employee’s then-current contribution level.

(iii)    the Company shall arrange for the Employee’s uninterrupted participation for three (3) years after the Termination Date in the Company’s major medical/dental insurance plan, which participation shall cease upon Employee’s eligibility for participation in a major medical/dental insurance plan of another employer;

(iv)    the Company shall cause the Employee to receive three (3) years age and service credit for eligibility for the Company’s retiree medical insurance coverage; and

(v)    the Company shall provide outplacement services at a cost not to exceed $50,000.00.

Each payment required to be made to the Employee pursuant to the foregoing provisions of this Section 7 shall be made by check drawn on an account of the Company at a bank located in the United States of America (unless the Employee has elected to have salary payments deposited directly by the Company to a bank account maintained by the Employee, in which event the Company shall make a direct deposit of the payment to that account), and shall be paid (x) if the Employee’s employment by the Company was terminated as a result of the Employee’s death, the Employee’s Disability or the Employee’s Retirement, not more than thirty (30) days immediately following the date of the occurrence of that event, and (y) if the Employee’s employment by the Company was terminated for any other reason, not more than ten (10) days immediately following the Termination Date.

SECTION 8.    SUCCESSORS.

If a Change of Control of the Company shall have occurred before the expiration of the term of this Agreement,

(a)    the Company shall not, directly or indirectly, consolidate with, merge into or sell or otherwise transfer its assets as an entirety or substantially as an entirety to, any person, or permit any person to consolidate with or merge into the Company, unless immediately after such consolidation, merger, sale or transfer, the Successor shall have assumed in writing the Company’s obligations under this Agreement and agreed to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place; and

(b)    not fewer than ten (10) days before the consummation of any consolidation of the Company with, merger by the Company into, or sale or other transfer by the Company of its assets as an entirety or substantially as an entirety to, any person, the Company shall give the Employee notice of that proposed transaction.

8

SECTION 9.    NOTICE.

Notices required or permitted to be given by either party pursuant to this Agreement shall be in writing and shall be deemed to have been given when delivered personally to the other party or when deposited with the United States Postal Service as certified or registered mail with postage prepaid and addressed:

(a)    if to the Employee, at the Employee’s address last shown on the Company’s records, and

(b)    if to the Company, at 1111 Bagby, Sky Lobby 2, Houston, Texas 77002, directed to the attention of the Company’s Chairman of the Board,

or, in either case, to such other address as the party to whom such notice is to be given shall have specified by notice given to the other party.

SECTION 10.    WITHHOLDING TAXES.

The Company may withhold from all payments to be paid to the Employee pursuant to this Agreement all taxes that, by applicable federal or state law, the Company is required to so withhold.

SECTION 11.    U.S. EXCISE TAXES.

If any payment or right accruing to the Employee from the Company or an Affiliate under this Agreement without the application of this Section 11 (“Total Payments”), would constitute a “parachute payment” (as defined in Section 280G of the Code (as defined in Section 20) and regulations thereunder), the severance benefit payable under this Agreement shall be reduced to the largest amount that will result in no portion of the amounts payable or rights accruing being subject to an excise tax under Section 4999 of the Code or being disallowed as a deduction under Section 280G of the Code. The determination of whether any reduction in the severance benefit payable is to apply shall be made by a public accounting firm chosen by the Company, at the expense of the Company. Such determination shall be made in good faith after consultation with the Employee and shall be conclusive and binding on the Employee. The Employee shall cooperate in good faith with said accounting firm in making such determination and providing the necessary information for this purpose. The foregoing provisions of this Section 11 shall apply only if after reduction for any applicable federal excise tax imposed by Section 4999 of the Code and federal, state or local income or employment taxes, the Total Payments accruing to the Employee would be less than the amount of the Total Payments as reduced under the foregoing provisions of this Section 11 and after reduction for only federal, state or local income or employment taxes. For the avoidance of doubt, the parties to this Agreement agree that this Section 11 explicitly modifies the U.S. Excise Tax treatment of benefits which may be payable or otherwise provided under any plan, program, policy, or practice of the Company or an Affiliate and any agreement or understanding that the Employee may have with the Company or an Affiliate.

Exhibit 95

Mine Safety Disclosure Exhibit

    Under the Dodd-Frank Wall Street Reform and Consumer Protection Act and the related rules promulgated thereunder by the United States Securities and Exchange Commission (SEC), each operator of a coal or other mine is required to disclose certain mine safety matters in its periodic reports filed with the SEC.

EOG Resources, Inc. (EOG) has sand mining facilities in Texas and Wisconsin, which have supported EOG's exploration and development operations. EOG's sand mining operations are subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects mining facilities on a regular basis and issues citations and orders when it believes a violation has occurred under the Mine Act.

EOG was the operator of record of the following sand mining facilities during the quarter ended June 30, 2021:

•Hood County Sand Plant - Hood County, TX (MSHA ID 41-04696);

•Rawhide Sand Plant - Hood County, TX (MSHA ID 41-04777); and

•Chippewa Falls Sand Plant - Chippewa County, WI (MSHA ID 47-03624).

__________

During the quarter ended June 30, 2021, EOG did not receive any of the following from MSHA: (i) a citation for a violation of a mandatory health or safety standard that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under Section 104 of the Mine Act; (ii) an order issued under Section 104(b) of the Mine Act; (iii) a citation or order for unwarrantable failure to comply with mandatory health or safety standards under Section 104(d) of the Mine Act; (iv) written notice of a flagrant violation under Section 110(b)(2) of the Mine Act; (v) an imminent danger order issued under Section 107(a) of the Mine Act; (vi) any proposed assessments under the Mine Act; (vii) written notice of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under Section 104(e) of the Mine Act; or (viii) written notice of the potential to have such a pattern. Moreover, during the quarter ended June 30, 2021, EOG did not experience a mining-related fatality.

In addition, as of June 30, 2021, EOG did not have any legal action pending before the Federal Mine Safety and Health Review Commission (Mine Commission), and did not have any legal actions instituted or resolved before the Mine Commission during the quarter ended June 30, 2021.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021 (EOG's 2020 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the three and six months ended June 30, 2021, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2021, EOG adopted the provisions of Accounting Standards Update (ASU) 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12). ASU 2019-12 amends certain aspects of accounting for income taxes, including the removal of specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and updates to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. The effects of ASU 2019-12 applicable to EOG were all required on a prospective basis. There was no impact upon adoption of ASU 2019-12 to its consolidated financial statements or related disclosures.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Lease and Well	$	11	$	15	$	25	$	30

Total	$	31	$	40	$	66	$	80

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provided for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

EOG's stockholders approved the EOG Resources, Inc. 2021 Omnibus Equity Compensation Plan (2021 Plan) at the 2021 Annual Meeting of Stockholders. Therefore, no further grants were made from the 2008 Plan from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, SARs, restricted stock and restricted stock units and other stock-based awards, up to an aggregate maximum of 20 million shares of common stock, plus any shares that are subject to outstanding awards under the 2008 Plan as of April 29, 2021, that are subsequently canceled, forfeited, expire or are otherwise not issued or are settled in cash. Under the 2021 Plan, grants may be made to employees and non-employee members of EOG's Board of Directors (Board). EOG's policy is to issue shares related to 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

At June 30, 2021, approximately 20 million shares of common stock remained available for grant under the 2021 Plan.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $9 million and $15 million during the three months ended June 30, 2021 and 2020, respectively, and $19 million and $29 million during the six months ended June 30, 2021 and 2020, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2021 and 2020 are as follows:

	Stock Options/SARs						ESPP
	Six Months Ended June 30,						Six Months Ended June 30,
	2021			2020			2021			2020
Weighted Average Fair Value of Grants	$	20.73		$	16.94		$	14.69		$	20.80
Expected Volatility	46.40		%	42.10		%	54.99		%	35.24		%
Risk-Free Interest Rate	0.36		%	0.93		%	0.09		%	1.56		%
Dividend Yield	2.87		%	1.94		%	3.41		%	1.56		%
Expected Life	5.2 years			5.1 years			0.5 years			0.5 years

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

The following table sets forth stock option and SAR transactions for the six-month periods ended June 30, 2021 and 2020 (stock options and SARs in thousands):

	Six Months Ended June 30, 2021			Six Months Ended June 30, 2020
	Number of Stock Options/SARs	Weighted Average Exercise Price		Number of Stock Options/SARs	Weighted Average Exercise Price
Outstanding at January 1	10,186	$	84.08	9,395	$	94.53
Granted	14	64.97		16	58.40
Exercised (1)	(239)	69.85		(23)	69.59
Forfeited	(234)	91.54		(389)	91.39
Outstanding at June 30 (2)	9,727	$	84.23	8,999	$	94.66
Vested or Expected to Vest (3)	9,421	$	84.91	8,670	$	94.67
Exercisable at June 30 (4)	6,023	$	97.08	4,963	$	94.61

(1)The total intrinsic value of stock options/SARs exercised during the six months ended June 30, 2021 and 2020 was $3.0 million and $0.4 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the exercise price of the stock options/SARs.

(2)The total intrinsic value of stock options/SARs outstanding at June 30, 2021 and 2020 was $114 million and $0.1 million, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at June 30, 2021 and 2020 was $106 million and $0.1 million, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at June 30, 2021 and 2020 was $16 million and zero, respectively. At June 30, 2021 and 2020, the weighted average remaining contractual life was 2.7 years.

At June 30, 2021, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $37 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 years.

Restricted Stock and Restricted Stock Units. Employees may be granted restricted (non-vested) stock and/or restricted stock units without cost to them. Stock-based compensation expense related to restricted stock and restricted stock units totaled $21 million and $24 million for the three months ended June 30, 2021 and 2020, respectively, and $45 million and $49 million for the six months ended June 30, 2021 and 2020, respectively.

The following table sets forth restricted stock and restricted stock unit transactions for the six-month periods ended June 30, 2021 and 2020 (shares and units in thousands):

	Six Months Ended June 30, 2021			Six Months Ended June 30, 2020
	Number of Shares and Units	Weighted Average Grant Date Fair Value		Number of Shares and Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	4,742	$	74.97	4,546	$	90.16
Granted	45	72.56		67	51.83
Released (1)	(523)	87.61		(304)	88.58
Forfeited	(47)	70.24		(36)	90.61
Outstanding at June 30 (2)	4,217	$	73.43	4,273	$	89.67

(1)The total intrinsic value of restricted stock and restricted stock units released during the six months ended June 30, 2021 and 2020 was $38 million and $13 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the restricted stock and restricted stock units are released.

(2)The total intrinsic value of restricted stock and restricted stock units outstanding at June 30, 2021 and 2020 was $352 million and $217 million, respectively.

At June 30, 2021, unrecognized compensation expense related to restricted stock and restricted stock units totaled $133 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.3 years.

Performance Units. EOG grants performance units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the performance units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the performance units granted could be outstanding. The fair value of the performance units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the performance unit grants totaled $1 million for each of the three months ended June 30, 2021 and 2020 and $2 million for each of the six months ended June 30, 2021 and 2020.

The following table sets forth the performance unit transactions for the six-month periods ended June 30, 2021 and 2020 (units in thousands):

	Six Months Ended June 30, 2021				Six Months Ended June 30, 2020
	Number of Units		Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	613		$	88.38	598	$	103.91
Granted	8		55.69		—	—
Granted for Performance Multiple (1)	19		113.81		66	119.10
Released (2)	(98)		113.81		(121)	123.56
Forfeited	—		—		—	—
Outstanding at June 30 (3)	542	(4)	$	84.23	543	$	101.38

(1)Upon completion of the Performance Period for the performance units granted in 2017 and 2016, a performance multiple of 125% and 150%, respectively, was applied to each of the grants resulting in additional grants of performance units in February 2021 and February 2020, respectively.

(2)The total intrinsic value of performance units released during the six months ended June 30, 2021 and 2020 was $6 million and $9 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the performance units are released.

(3)The total intrinsic value of performance units outstanding at June 30, 2021 and 2020 was approximately $45 million and $28 million, respectively.

(4)Upon the application of the relevant performance multiple at the completion of each of the remaining Performance Periods, a minimum of 76,785 and a maximum of 1,007,705 performance units could be outstanding.

At June 30, 2021, unrecognized compensation expense related to performance units totaled $6 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.7 years.

Debt Disclosure [Abstract]

Long-Term Debt and Common Stock

Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at June 30, 2021 and December 31, 2020, and did not utilize any commercial paper borrowings during the six months ended June 30, 2021 and 2020.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-capitalization (as such terms are defined in the Agreement) of no greater than 65%. At June 30, 2021, EOG was in compliance with this financial covenant. At June 30, 2021 and December 31, 2020, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at June 30, 2021, would have been 1.00% and 3.25%, respectively.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

Common Stock. On February 25, 2021, EOG's Board increased the quarterly cash dividend on the common stock from the previous $0.375 per share to $0.4125 per share, effective beginning with the dividend paid on April 30, 2021, to stockholders of record as of April 16, 2021. On May 6, 2021, EOG's Board declared a special cash dividend on the common stock of $1.00 per share in addition to a quarterly dividend of $0.4125 per share. Both the special cash dividend and the quarterly cash dividend are payable on July 30, 2021 to stockholders of record as of July 16, 2021.

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at June 30, 2021 and December 31, 2020 (in millions):

See Note 12 for the balance sheet amounts and classification of EOG's financial derivative instruments at June 30, 2021 and December 31, 2020.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) significant Level 3 inputs, including future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At June 30, 2021 and December 31, 2020, respectively, EOG had outstanding $4,890 million and $5,640 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,654 million and $6,505 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Risk Management Activities

Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of June 30, 2021. Crude oil and NGL volumes are presented in thousand barrels per day (MBbld) and prices are presented in dollars per barrel ($/Bbl). Natural gas volumes are presented in million British Thermal Units per day (MMBtud) and prices are presented in dollars per million British Thermal Units ($/MMBtu).

(1)    The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $430 million, partially offset by gross assets of $34 million, at June 30, 2021.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposures to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net liability position at June 30, 2021 and a net asset position at December 31, 2020. EOG had $107 million of collateral posted and no collateral held at June 30, 2021, and had no collateral posted or held at December 31, 2020.
