Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared using generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by generally accepted accounting principles for annual financial statements and should be read together with the annual financial statements and notes thereto included in the Annual Report. The accompanying unaudited condensed consolidated financial statements and related notes present the condensed consolidated financial position of the Company as of March 31, 2020 and December 31, 2019, and the results of operations, cash flows, and equity of the Company as of and for the three months ended March 31, 2020 and 2019. The interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim period. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results of operations expected for the entire fiscal year ended December 31, 2020. Further, these estimates and other factors, including those outside the Company’s control, such as the impact of sustained lower commodity prices, could have a significant adverse impact to the Company’s financial condition, results of operations and cash flows. All intercompany amounts have been eliminated in the presentation of the unaudited condensed consolidated financial statements of the Company. Comprehensive income is not reported due to the absence of items of other comprehensive income or loss during the periods presented. The Company’s operations are organized into a single reportable segment, which consists of hydraulic fracturing services and goods.
Credit Losses	Recently Adopted Accounting Standards Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. Specifically, this new guidance requires using a forward looking, expected loss model for trade and other receivables, held-to-maturity debt securities, loans, and other instruments. Under ASU 2016-13, a Company recognizes, as an allowance, the estimate of lifetime expected credit losses, which is to result in more timely recognition of such losses. On January 1, 2020, the Company adopted ASU 2016-13 using the modified-retrospective approach, which allows for a cumulative-effect adjustment to the consolidated condensed balance sheet as of the beginning of the first reporting period in which the guidance is effective. Periods prior to the adoption date that are presented for comparative purposes are not adjusted. The Company continuously evaluates customers based on risk characteristics, such as historical losses and current economic conditions. Due to the cyclical nature of the oil and gas industry, the Company often evaluates its customers’ estimated losses on a case-by-case basis. While there was no impact to the financial statements as a result of adoption of ASU 2016-13, as a result of deteriorating economic conditions for the oil and gas industry brought on by the COVID-19 pandemic, during the first quarter of 2020, the Company recorded a provision for credit losses of $2.5 million, included in general and administrative expenses in the accompanying condensed consolidated statement of income, in accordance with the new standard. Refer to “Credit Risk” within Note 7—Fair Value Measurements and Financial Instruments for additional disclosures required under ASU 2016-13. Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which eliminates, adds and modifies certain disclosure requirements for fair value measurements. The Company adopted ASU 2018-13 on January 1, 2020 and determined the adoption of this standard did not impact the Company’s condensed consolidated financial statements. Refer to Note 7—Fair Value Measurements and Financial Instruments for the disclosures required under ASU 2018-13. Recently Issued Accounting Standards Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform, which provides temporary optional guidance to companies impacted by the transition away from the London Interbank Offered Rate (“LIBOR”). The guidance provides certain expedients and exceptions to applying GAAP in order to lessen the potential accounting burden when contracts, hedging relationships, and other transactions that reference LIBOR as a benchmark rate are modified. This guidance is effective upon issuance and expires on December 31, 2022. The Company is currently assessing the impact of the LIBOR transition and this ASU on the Company’s financial statements.
