Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization Liberty Oilfield Services Inc. (the “Company”) was incorporated as a Delaware corporation on December 21, 2016, to become a holding corporation for Liberty Oilfield Services New HoldCo LLC (“Liberty LLC”) and its subsidiaries upon completion of a corporate reorganization (the “Corporate Reorganization”) and planned initial public offering of the Company (“IPO”). The Company has no material assets other than its ownership of units in Liberty LLC (“Liberty LLC Units”). Please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the U.S. Securities and Exchange Commission on February 27, 2020 (the “Annual Report”) for additional information on the Corporate Reorganization and IPO that were completed on January 17, 2018. The Company, together with its subsidiaries, is a multi-basin provider of hydraulic fracturing services and goods, with a focus on deploying the latest technologies in the technically demanding oil and gas reservoirs in which it operates, principally in North Dakota, Colorado, New Mexico, Wyoming, and Texas. 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.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies 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. Fleet Start-up Costs The Company incurs start-up costs to commission a new fleet or district. These costs include hiring and training of personnel, and acquisition of consumable parts and tools. Start-up costs are expensed as incurred, and are reflected in general and administrative expenses in the condensed consolidated statements of income. Start-up costs for the three months ended March 31, 2020 and 2019 were $0.0 million and $1.1 million, respectively. The Company deployed one fleet in each quarter ended March 31, 2020 and 2019. The total amount of start-up costs incurred for the commissioning of each new fleet depends primarily on the number and timing of hiring additional personnel to staff such fleets, and such costs may not be entirely incurred in the same period as the fleet is deployed. The terms and conditions of the Credit Facilities, defined herein, between the Company and its lenders provides for the add-back of costs or expenses incurred in connection with the acquisition, deployment, and opening of any new hydraulic fracturing fleet or district in the computation of certain financial covenants (see Note 6—Debt). Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. These reclassifications had no effect on the previously reported net income.

During the first quarter of 2020, as a result of negative market indicators including the COVID-19 pandemic, the increased supply of low-priced oil, and customer cancellations, the Company concluded these triggering events could indicate possible impairment of property and equipment. The Company performed a quantitative and qualitative impairment analysis and determined that no impairment had occurred as of March 31, 2020. Such analysis required management to make estimates and assumptions based on historical data and consideration of future market conditions. Given the uncertainty inherent in any projection, heightened by the possibility of unforeseen additional effects of COVID-19, actual results may differ from the estimates and assumptions used, or conditions may change, which could result in impairment charges in the future.

Leases [Abstract]
Leases	Leases The Company has operating and finance leases primarily for vehicles, equipment, railcars, office space, and facilities. The terms and conditions for these leases vary by the type of underlying asset. Certain leases include variable lease payments for items such as property taxes, insurance, maintenance, and other operating expenses associated with leased assets. Payments that vary based on an index or rate are included in the measurement of lease assets and liabilities at the rate as of the commencement date. All other variable lease payments are excluded from the measurement of lease assets and liabilities, and are recognized in the period in which the obligation for those payments is incurred.

Leases	Leases The Company has operating and finance leases primarily for vehicles, equipment, railcars, office space, and facilities. The terms and conditions for these leases vary by the type of underlying asset. Certain leases include variable lease payments for items such as property taxes, insurance, maintenance, and other operating expenses associated with leased assets. Payments that vary based on an index or rate are included in the measurement of lease assets and liabilities at the rate as of the commencement date. All other variable lease payments are excluded from the measurement of lease assets and liabilities, and are recognized in the period in which the obligation for those payments is incurred.

ABL Facility Under the terms of the ABL Facility, up to $250.0 million may be borrowed, subject to certain borrowing base limitations based on a percentage of eligible accounts receivable and inventory. As of March 31, 2020, the borrowing base was calculated to be $203.0 million, and the Company had no borrowings outstanding, except for a letter of credit in the amount of $0.3 million, with $202.7 million of remaining availability. Borrowings under the ABL Facility bear interest at LIBOR or a base rate, plus an applicable LIBOR margin of 1.5% to 2% or base rate margin of 0.5% to 1%, as defined in the ABL Facility credit agreement. The average monthly unused commitment is subject to an unused commitment fee of 0.375% to 0.5%. Interest and fees are payable in arrears at the end of each month, or, in the case of LIBOR loans, at the end of each interest period. The ABL Facility matures on the earlier of (i) September 19, 2022 and (ii) to the extent the debt under the Term Loan Facility remains outstanding, 90 days prior to the final maturity of the Term Loan Facility, which matures on September 19, 2022. Borrowings under the ABL Facility are collateralized by accounts receivable and inventory, and further secured by the Company, Liberty LLC, and R/C IV Non-U.S. LOS Corp. (“R/C IV”), a Delaware corporation and a subsidiary of the Company, as parent guarantors. Term Loan Facility The Term Loan Facility provides for a $175.0 million term loan, of which $109.6 million remained outstanding as of March 31, 2020. Amounts outstanding bear interest at LIBOR or a base rate, plus an applicable margin of 7.625% or 6.625%, respectively, and the weighted average on borrowings was 8.6% as of March 31, 2020. The Company is required to make quarterly principal payments of 1% per annum of the outstanding principal balance, commencing on December 31, 2017, with final payment due at maturity on September 19, 2022. The Term Loan Facility is collateralized by the fixed assets of Liberty Oilfield Services LLC (“LOS”) and its subsidiaries, and is further secured by the Company, Liberty LLC, and R/C IV, as parent guarantors. The Credit Facilities include certain non-financial covenants, including but not limited to restrictions on incurring additional debt and certain distributions. Moreover, the ability of the Company to incur additional debt and to make distributions is dependent on maintaining a maximum leverage ratio. The Term Loan Facility requires mandatory prepayments upon certain dispositions of property or issuance of other indebtedness, as defined, and annually a percentage of excess cash flow (25% to 50%, depending on leverage ratio, of consolidated net income less capital expenditures and other permitted payments, commencing with the year ending December 31, 2018). Certain mandatory prepayments and optional prepayments are subject to a prepayment premium of 3% of the prepaid principal declining annually to 1% during the first three years of the term of the Term Loan Facility. The Credit Facilities are not subject to financial covenants unless liquidity, as defined in the respective credit agreements, falls below a specific level. During a covenant measurement period under the ABL Facility, the Company is required to maintain a minimum fixed charge coverage ratio, as defined, of 1.0 to 1.0 for each period if excess availability is less than 10% of the borrowing base or $12.5 million, whichever is greater. During a covenant measurement period under the Term Loan Facility, the Company is required to maintain a minimum fixed charge coverage ratio, as defined, of 1.2 to 1.0 for each trailing twelve-month period if the Company’s liquidity, as defined, is less than $25.0 million for at least five consecutive business days. Based on liquidity as defined in the respective agreements, the Company was not subject to financial covenants as of March 31, 2020 and thus was in compliance as of March 31, 2020. Maturities of debt are as follows: ($ in thousands) Remainder of 2020 $ 1,312 2021 $ 1,750 2022 $ 106,466 2023 $ — 2024 $ — $ 109,528

Fair Value Measurements and Fin

Fair Value Measurements and Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements and Financial Instruments	Fair Value Measurements and Financial Instruments The fair values of the Company’s assets and liabilities represent the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction at the reporting date. These fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company’s own judgments about the assumptions that market participants would use in pricing the asset or liability. The Company discloses the fair values of its assets and liabilities according to the quality of valuation inputs under the following hierarchy: • Level 1 Inputs: Quoted prices (unadjusted) in an active market for identical assets or liabilities. • Level 2 Inputs: Inputs other than quoted prices that are directly or indirectly observable. • Level 3 Inputs: Unobservable inputs that are significant to the fair value of assets or liabilities. The classification of an asset or liability is based on the lowest level of input significant to its fair value. Those that are initially classified as Level 3 are subsequently reported as Level 2 when the fair value derived from unobservable inputs is inconsequential to the overall fair value, or if corroborating market data becomes available. Assets and liabilities that are initially reported as Level 2 are subsequently reported as Level 3 if corroborating market data is no longer available. Transfers occur at the end of the reporting period. There were no transfers into or out of Levels 1, 2, and 3 during the three months ended March 31, 2020 and 2019. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, notes receivable, accounts payable, accrued liabilities, long-term debt, and finance and operating lease obligations. These financial instruments do not require disclosure by level. The carrying values of all of the Company’s financial instruments included in the accompanying condensed consolidated balance sheets approximated or equaled their fair values at March 31, 2020 and December 31, 2019. • The carrying values of cash and cash equivalents, accounts receivable and accounts payable (including accrued liabilities) approximated fair value at March 31, 2020 and December 31, 2019, due to their short-term nature. • The carrying value of amounts outstanding under long-term debt agreements with variable rates approximated fair value at March 31, 2020 and December 31, 2019, as the effective interest rates approximated market rates. Nonrecurring Measurements Certain assets are measured at fair value on a nonrecurring basis. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. These assets consist of notes receivable—related party from the Affiliate, as defined and described in Note 12—Related Party Transactions. The note was initially recorded for the trade receivables, created in the normal course of business, due from the Affiliate as of the Agreement Date, as defined in Note 12—Related Party Transactions. There were no identified events or changes in circumstances that had a significant adverse effect on the fair value of the note receivable. The note is classified as Level 3 in the fair value hierarchy as the inputs to the determination of fair value are based upon unobservable inputs. The note was paid in full in January 2020, and a s of March 31, 2020 and December 31, 2019, notes receivable—related party from the Affiliate totaled $0 and $2.5 million, respectively. Recurring Measurements The fair values of the Company’s cash equivalents measured on a recurring basis pursuant to Accounting Standards Codification (“ASC”) 820-10 Fair Value Measurements and Disclosures are carried at estimated fair value. Cash equivalents consist of money market accounts which the Company has classified as Level 1 given the active market for these accounts. As of March 31, 2020 and December 31, 2019, the Company had cash equivalents, measured at fair value, of $41.2 million and $86.9 million, respectively. Nonfinancial assets The Company estimates fair value to perform impairment tests as required on long-lived assets. The inputs used to determine such fair value are primarily based upon internally developed cash flow models and would generally be classified within Level 3 in the event that such assets were required to be measured and recorded at fair value within the financial statements. Although a triggering event occurred during the three months ended March 31, 2020 (see Note 4—Property and Equipment), no such measurements were required as of March 31, 2020 and December 31, 2019. Credit Risk The Company’s financial instruments exposed to concentrations of credit risk consist primarily of cash and cash equivalents and trade receivables. The Company’s cash and cash equivalent balances on deposit with financial institutions total $56.5 million and $112.7 million as of March 31, 2020 and December 31, 2019, respectively, which exceeded FDIC insured limits. The Company regularly monitors these institutions’ financial condition. The majority of the Company’s customers have payment terms of 45 days or less. As of March 31, 2020 and December 31, 2019, customer A accounted f or 11% and customer B accounted for 12% of total accounts receivable and unbilled revenue, respectively. The Company mitigates the associated credit risk by performing credit evaluations and monitoring the payment patterns of its customers. During the three months ended March 31, 2020, customer A accounted for 15% of total revenue, and during the three months ended March 31, 2019, customer s B and C accounted for 22% of total revenue. As of March 31, 2020 the Company had $3.6 million allowance for credit losses. The current period provision of $2.5 million was the result of the application of ASU 2016-13 (see “Credit Losses” within Note 2—Significant Accounting Policies) to the Company’s accounts receivables as of March 31, 2020 in consideration of both historic collection experience and the expected impact of currently deteriorating economic conditions for the oil and gas industry. The Company applied historic loss factors to its receivable portfolio segments that were not expected to be further impacted by current economic developments, and an additional economic conditions factor to portfolio segments anticipated to experience greater losses in the current economic environment. The majority of the Company’s allowance for credit losses relates to one customer currently in bankruptcy for which expected credit losses were individually evaluated. While the Company has not experienced significant credit losses in the past and has not yet seen material changes to the payment patterns of its customers, the Company cannot predict with any certainty the degree to which the impacts of COVID-19, including the potential impact of periodically adjusted borrowing base limits, level of hedged production, or unforeseen well shut-ins may affect the ability of its customers to timely pay receivables when due. Accordingly, in future periods, the Company may revise its estimates of expected credit losses. Previously, during the three months ended December 31, 2019, the Company had recorded a $1.1 million allowance for credit losses related to one specific entity engaged in the business of oil and gas exploration and production that has filed for bankruptcy.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is a corporation and is subject to U.S. federal, state, and local income tax on its share of Liberty LLC’s taxable income. The effective combined U.S. federal and state income tax rate applicable to the Company for the three months ended March 31, 2020 was 9.7% , compared to 15.2% for the period ended March 31, 2019. The Company’s effective tax rate is significantly less than the statutory federal tax rate of 21.0% primarily because no taxes are payable by the Company for the non-controlling interest’s share of Liberty LLC’s pass-through results for federal, state, and local income tax reporting. The Company recognized income tax expense of $0.3 million an d $6.1 million during the three months ended March 31, 2020 and 2019, respectively. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted and signed into law. The CARES Act contains modifications to the rules around federal income tax net operating loss (“NOL”) rules. The CARES Act permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. Certain provisions of the CARES Act impact the 2019 income tax provision computations of the Company and are reflected in the first quarter of 2020, or the period of enactment. The Company has applied for the NOL carryback refund to recover a portion of cash taxes paid in 2018, for which $9.3 million is reflected as a component of prepaids and other current assets in the accompanying condensed consolidated balance sheet, and for which a portion will be due to TRA Holders (as defined below), an estimate of which is reflected as current TRA payable. Tax Receivable Agreements In connection with the IPO, on January 17, 2018, the Company entered into two Tax Receivable Agreements (the “TRAs”) with R/C Energy IV Direct Partnership, L.P. and the then existing owners that continued to own Liberty LLC Units (each such person and any permitted transferee, a “TRA Holder” and together, the “TRA Holders”). The TRAs generally provide for the payment by the Company of 85% of the net cash savings, if any, in U.S. federal, state, and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the IPO as a result, as applicable to each TRA Holder, of (i) certain increases in tax basis that occur as a result of the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of such TRA Holder’s Liberty LLC Units in connection with the IPO or pursuant to the exercise of redemption or call rights, (ii) any net operating losses available to the Company as a result of the Corporate Reorganization, and (iii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under the TRAs. During the three months ended March 31, 2020 there were no redemptions of Liberty LLC Units and shares of Class B Common Stock. During the three months ended March 31, 2019, redemptions of Liberty LLC Units and shares of Class B Common Stock resulted in an increase of $5.1 million in amounts payable under the TRAs, and a net increase of $6.0 million in deferred tax assets, all of which were recorded through equity. At March 31, 2020 and December 31, 2019, the Company ’ s liability under the TRAs was $48.3 million and $50.3 million, respectively, a portion of which is presented as a component of current liabilities of $5.7 million and $1.8 million, respectively, a portion of which is presented as a component of long-term liabilities of $42.6 million and $48.5 million, respectively, and the related deferred tax assets totaled $49.9 million and $49.9 million, respectively. The Company made a tax benefit payment of $2.0 million to the Company’s TRA Holders, related to tax benefits realized during the calendar year ended December 31, 2019 and payable pursuant to the Company’s TRAs during the three months ended March 31, 2020.

As of March 31, 2020 and December 31, 2019, the Company ’ s current liabilities under the TRAs payable to R/C IV Liberty Holdings, L.P. and R/C IV were $3.0 million and $1.3 million, respectively, included in accrued interest and other and non-current liabilities were $20.6 million and $23.8 million, respectively, in payable pursuant to tax receivable agreements in the accompanying condensed consolidated balance sheets. Liberty Resources LLC, an oil and gas exploration and production company, and its successor entity (collectively, the “Affiliate”) has certain common ownership and management with the Company. The amounts of the Company’s revenue related to hydraulic fracturing services provided to the Affiliate for the three months ended March 31, 2020 and 2019 was $0.0 million and $6.3 million, respectively . As of March 31, 2020 and December 31, 2019, $1.4 million and $7.1 million, respectively, of the Company’s accounts receivable—related party was with the Affiliate. On June 24, 2019 (the “Agreement Date”), the Company entered into an agreement with the Affiliate to amend payment terms for outstanding invoices due as of the Agreement Date to be due on July 31, 2020. On September 30, 2019, the agreement was amended to extend the due date for remaining amounts outstanding to October 31, 2020. Amounts outstanding from the Affiliate as of the Agreement Date were $15.6 million. The amount outstanding, including all accrued interest, was paid in full in January 2020. As of March 31, 2020 and December 31, 2019, amounts outstanding under the amended payment terms from the Affiliate ar e $0 and $2.5 million, respectively, all of which is presented in accounts and notes receivable—related party in the accompanying condensed consolidated balance sheet. The balance outstanding is subject to interest at 13% annual percent yield, retroactively applied to the respective invoice date. During the three months ended March 31, 2020, interest income from the Affiliate wa s $0.2 million , and accrued interest as of March 31, 2020 and December 31, 2019 was $0. Receivables earned for services performed after the Agreement Date continue to be subject to normal 30-day payment terms, provided that any amount unpaid after 60 days will be subject to 13% interest. Liberty Holdings entered into an advisory agreement dated December 30, 2011 with R/C, in which R/C agreed to provide certain administrative advisory services to Liberty Holdings. The Company incurre d no serv ice fees during the three months ended March 31, 2020 and 2019. The advisory services agreement was terminated pursuant to an agreement effective as of January 11, 2018. On January 11, 2018, Liberty Holdings, R/C, and other parties entered into a Master Reorganization Agreement that, among other things, crystallized the “waterfall” provisions of Article VI of the Third Amended and Restated Limited Liability Agreement of Liberty Holdings, dated October 11, 2016 (the “Holdings LLC Agreement”) in connection with the IPO. As part of this crystallization, R/C and affiliated entities (collectively, the “R/C Affiliates”) received shares of Class A Common Stock, including 117,647 shares of Class A Common Stock (such 117,647 shares referred to as the “Issued Shares”) to compensate R/C Affiliates for certain accrued preferred returns but which would not have been issued had the $2.0 million in fees owed under the advisory agreement been paid in cash. Had this fee been paid in cash on or prior to January 11, 2018, R/C and Liberty Holdings acknowledge that R/C Affiliates would not have received the Issued Shares in the crystallization pursuant to the provisions of the Holdings LLC Agreement. Subsequently, during the fourth quarter of 2018, R/C asserted that certain provisions of the termination of services agreement provided for R/C to receive $2.0 million in cash as payment of those accrued fees. To resolve this matter, the Company agreed to pay R/C Affiliates $2.0 million in cash in exchange for the purchase, at the IPO price, or return of the Issued Shares and $0.3 million for interest and the settlement of the matter. Accordingly, $2.3 million was recorded as accrued liabilities—related party in the accompanying condensed consolidated balance sheet as of December 31, 2018 and subsequently paid in January 2019. The purchased and returned shares of Class A Common Stock were canceled and retired, and the Company does not expect to incur future expense related to the advisory agreement or termination thereof. During 2016, Liberty Holdings entered into a future commitment to invest and become a non-controlling minority member in Proppant Express Investments, LLC (“PropX Investments”), the owner of Proppant Express Solutions, LLC (“PropX”), a provider of proppant logistics equipment. LOS was party to a services agreement (the “PropX Services Agreement”) whereby LOS was to provide certain administrative support functions to PropX, and LOS was to purchase and lease proppant logistics equipment from PropX. The PropX Services Agreement was terminated on May 29, 2018, however the Company continues to purchase and lease equipment from PropX under certain lease agreements. For the three months ended March 31, 2020 and 2019, the Company leased proppant logistics equipment for $2.6 million and $2.4 million, respectively. The Company purchased no proppant logistics equipment for the three months ended March 31, 2020 and 2019. P ayables to PropX as of March 31, 2020 and December 31, 2019 were $0.9 million a nd $0.8 million, respectively. In April 2020, the Company and PropX amended certain logistics equipment leases to provide for a reduced monthly rate for the remaining lease term while also extending the term of those leases for an additional year (See Note 14–Subsequent Events for additional information).

Commitments and Contingencies	Commitments & Contingencies Purchase Commitments (tons and gallons are not in thousands) The Company enters into purchase and supply agreements to secure supply and pricing of proppants and chemicals. As of March 31, 2020 and December 31, 2019, the agreements provide pricing and committed supply sources for the Company to purchas e 5,462,750 and 7,978,300 tons, respectively, of proppant through February 1, 2022. Amounts above also include commitments to pay for transport fees on minimum amounts of proppants or railcars. Additionally, related proppant transload service commitments extend through 2025. As of March 31, 2020 and December 31, 2019, the Company also had agreements that provide pricing and committed supply source for the purchase of 1,831,500 and 3,339,534 gallons, respectively, of chemicals through December 31, 2020. Future proppant, including rail car transport, and chemical commitments based on Company forecasts are as follows: ($ in thousands) Remainder of 2020 $ 104,758 2021 80,237 2022 11,740 2023 9,524 2024 10,268 Thereafter 7,664 $ 224,191 Certain supply agreements contain a clause whereby in the event that the Company fails to purchase minimum volumes, as defined in the agreement, during a specific time period, a shortfall fee may apply. In circumstances where the Company does not make the minimum purchases required under the contract, the Company and its suppliers have a history of amending such minimum purchase contractual terms and in rare cases does the Company incur such shortfall fees. If the Company were unable to make any of the minimum purchases and the Company and its suppliers cannot come to an agreement to avoid such fees, the Company could incur shortfall fees in the amounts of $75.6 million, $43.2 million, $11.6 million, $9.5 million, $10.3 million, and $7.7 million for the remainder of 2020 and years ended 2021, 2022, 2023, 2024, and thereafter, respectively. Based on forecasted levels of activity, the Company does not currently expect to incur significant shortfall fees. Litigation Securities Class Actions On March 11, 2020, Marshall Cobb, on behalf of himself and all other persons similarly situated, filed a putative class action lawsuit in the state District Court of Denver County, Colorado against the Company and certain officers and board members of the Company along with other defendants in connection with the IPO (the “Cobb Complaint”). The Cobb Complaint alleges that the Company and certain officers and board members of the Company violated Section 11 of the Securities Act of 1933 by virtue of inaccurate or misleading statements allegedly contained in the registration statement filed in connection with the IPO and requests unspecified damages and costs. The Cobb Plaintiffs also allege control person liability claims under Section 15 of the Securities Act of 1933 against certain officers and board members of the Company and other defendants. On April 3, 2020, Marc Joseph, on behalf of himself and all other persons similarly situated, filed a putative class action lawsuit in the United States District Court in Denver, Colorado against the Company and certain officers and board members of the Company along with other defendants in connection with the IPO and requests unspecified damages and costs (the “Joseph Complaint,” and collectively with the Cobb Complaint, the “Securities Lawsuits”). The Joseph Complaint, which is based on similar factual allegations made in the Cobb Complaint, alleges that the defendants violated Sections 11 and 12(a)(2) of the Securities Act of 1933 by virtue of inaccurate or misleading statements allegedly contained in the registration statement and prospectus filed in connection with the IPO. The Joseph Complaint also alleges control person liability claims under Section 15 of the Securities Act of 1933 against certain officers and board members of the Company and other defendants. The Company has hired counsel and plans to vigorously defend against the allegations in the Securities Lawsuits. Other Litigation In addition to the matters described above, from time to time, the Company is subject to legal and administrative proceedings, settlements, investigations, claims and actions. The Company’s assessment of the likely outcome of litigation matters is based on its judgment of a number of factors including experience with similar matters, past history, precedents, relevant financial and other evidence and facts specific to the matter. Notwithstanding the uncertainty as to the final outcome, based upon the information currently available, management does not believe any matters in aggregate will have a material adverse effect on its financial position or results of operations.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In April 2020, the Company conducted layoffs in response to customer work cancellations as a direct result of declining oil prices and reduced demand from the impact of global efforts to combat COVID-19. In the second quarter of 2020, the Company expects to record one-time severance costs of approximately $7.4 million. Additionally, in April 2020, the Company and PropX amended certain logistics equipment leases to provide for a reduced monthly rate for the remaining lease term while also extending the term of those leases for an additional year (See Note 12–Related Party Transactions). The amendment results in approximately $1.0 million of reduced lease payments over the remaining portion of the original lease term. During the second quarter of 2020, in accordance with ASC Topic 842, Leases , the Company expects to record approximately $3.0 million of additional operating lease right-of-use assets and corresponding operating lease liabilities.

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.
Recently Issued Accounting Standards
Fleet Start-up Costs	Fleet Start-up Costs The Company incurs start-up costs to commission a new fleet or district. These costs include hiring and training of personnel, and acquisition of consumable parts and tools. Start-up costs are expensed as incurred, and are reflected in general and administrative expenses in the condensed consolidated statements of income. Start-up costs for the three months ended March 31, 2020 and 2019 were $0.0 million and $1.1 million, respectively. The Company deployed one fleet in each quarter ended March 31, 2020 and 2019. The total amount of start-up costs incurred for the commissioning of each new fleet depends primarily on the number and timing of hiring additional personnel to staff such fleets, and such costs may not be entirely incurred in the same period as the fleet is deployed.
