An accounting standards update revised the definition of proved oil and gas reserves to require that the average, first-day-of-the-month price during the 12-month period before the end of the year rather than the year-end price, must be used when estimating whether reserve quantities are economic to produce. This same 12-month average price is also used in calculating the aggregate amount of (and changes in) future cash inflows related to the standardized measure of discounted future net cash flows. The rules also allow for the use of reliable technologies to estimate proved oil, natural-gas and natural-gas liquids (NGLs) reserves if those technologies have been demonstrated to result in reliable conclusions about reserve volumes.        The unaudited supplemental information on oil and gas exploration and production activities for 2010 and 2009 has been presented in accordance with the revised reserve estimation and disclosure rules, which were not applied retrospectively. The 2007 and 2008 data is presented in accordance with Financial Accounting Standards Board (FASB) oil and gas disclosure requirements effective during those periods. However, historical information has been reclassified to conform to the geographic areas required to be disclosed under the revised accounting standard. Disclosures by geographic area include the United States and International. The International geographic area consists of proved reserves located in Algeria, China and Ghana.        The effect of applying the new definition of reliable technology and other non-price related aspects of the updated rules did not significantly impact 2009 net proved reserve volumes, nor does it have a significant impact on 2010 net proved reserve volumes. Approximately 1% and 3% of the Company's total proved reserves, as of year-end 2009 and 2010, respectively, are supported by the use of reliable technologies.Oil and Gas Reserves        The reserve disclosures that follow reflect estimates of proved reserves, proved developed reserves and proved undeveloped reserves, net of third-party royalty interests, of natural gas, crude oil and condensate, and NGLs owned at each year end and changes in proved reserves during each of the last three years. Natural-gas volumes are in billions of cubic feet (Bcf) at a pressure base of 14.73 pounds per square inch and volumes for oil, condensate and NGLs are in millions of barrels (MMBbls). Total volumes are presented in millions of barrels of oil equivalent (MMBOE). For this computation, one barrel is assumed to be the equivalent of 6,000 cubic feet of natural gas. Shrinkage associated with NGLs has been deducted from the natural-gas reserve volumes.       Reserves for international locations are calculated in accordance with the terms of their respective agreements. The international reserves include estimated quantities allocated to Anadarko for recovery of costs and income taxes and Anadarko's net equity share after recovery of such costs.        The Company's estimates of proved reserves are made using available geological and reservoir data as well as production performance data. These estimates are reviewed annually by internal reservoir engineers and revised, either upward or downward, as warranted by additional data. Revisions are necessary due to changes in, among other things, reservoir performance, prices, economic conditions and governmental restrictions, as well as changes in the expected recovery associated with infill drilling.       During 2010, Anadarko added 83 MMBOE of proved reserves primarily as the result of successful drilling in the United States. Reserve revisions for 2010 include an increase of 246 MMBOE primarily related to successful infill drilling in the large onshore natural-gas plays, such as the Greater Natural Buttes, Wattenberg and Pinedale fields (where the reserve bookings for the infill wells are treated as a positive revision), and an increase of 29 MMBOE driven by higher oil and gas prices. Sales of proved reserves in place were 6 MMBOE, related to onshore domestic and international assets. Acquisitions of proved reserves in place were 1 MMBOE, related to onshore domestic assets.        In 2009, Anadarko added 70 MMBOE of proved reserves primarily as the result of successful drilling in the United States and international locations. Reserve revisions for 2009 included an increase of 212 MMBOE primarily related to large onshore natural-gas plays, such as the Greater Natural Buttes and Pinedale fields, as a result of successful infill drilling. The revisions include a decrease of 39 MMBOE driven by lower natural-gas prices. Sales and acquisitions of proved reserves in place were 24 MMBOE and 32 MMBOE, respectively, related to onshore domestic assets.        In 2008, Anadarko added 96 MMBOE of proved reserves primarily as a result of successful drilling of development and appraisal wells in the United States. Reserve revisions for 2008 included an increase of 194 MMBOE primarily as a result of successful infill drilling related to the large onshore natural-gas plays, such as the Greater Natural Buttes, Wattenberg and Pinedale fields, in addition to positive revisions to the Peregrino heavy-oil field offshore Brazil, which was sold in 2008, partially offset by a decrease of 102 MMBOE related to price impacts for oil and NGLs. Sales of proved reserves in place for 2008 totaled 137 MMBOE, related to properties located in the United States and Brazil.<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 9px"><td style="width: 10px;

Net revenues from production include only the revenues from the production and sale of natural gas, oil, condensate and NGLs. Gains on property dispositions represent net gains on sales of oil and gas properties. Reversal of accrual for Deepwater Royalty Relief Act (DWRRA) dispute represents the reversal of previously recorded liabilities for royalties due on leases subject to litigation with the Department of Interior as described in Note 15—Contingencies in the Notes to Consolidated Financial Statements. Production costs are those incurred to operate and maintain wells and related equipment and facilities used in oil and gas operations. Exploration expenses include dry hole costs, leasehold impairments, geological and geophysical expenses, and the costs of retaining unproved leaseholds. Income tax expense is calculated by applying the current statutory tax rates to the revenues after deducting costs, which include depreciation, depletion and amortization allowances, after giving effect to permanent differences. The results of operations exclude general office overhead and interest expense attributable to oil and gas activities.<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 18px"><td colspan="2" style="width: 375px;

Prices used for all periods are adjusted only for fixed and determinable amounts under provisions in existing contracts. Estimated future net cash flows for all periods presented are reduced by estimated future development, production, abandonment and dismantlement costs based on existing costs, assuming continuation of existing economic conditions, and by estimated future income tax expense. These estimates also include assumptions about the timing of future production of proved reserves, and timing of future development, production costs, and abandonment and dismantlement. Income tax expense, both U.S. and foreign, is calculated by applying the existing statutory tax rates, including any known future changes, to the pretax net cash flows giving effect to any permanent differences and reduced by the applicable tax basis. The effect of tax credits is considered in determining the income tax expense. The 10-percent discount factor is prescribed by United States Generally Accepted Accounting Principles.        The present value of future net cash flows does not purport to be an estimate of the fair value of Anadarko's proved reserves. An estimate of fair value would also take into account, among other things, anticipated changes in future prices and costs, the expected recovery of reserves in excess of proved reserves and a discount factor more representative of the time value of money and the risks inherent in producing oil and natural gas. Significant changes in estimated reserve volumes or commodity prices could have a material effect on the Company's Consolidated Financial Statements. Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 18px"><td style="width: 376px;
