Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Oil States International, Inc. and its subsidiaries (referred to in this report as "we" or the "Company") have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "Commission") pertaining to interim financial information. Certain information in footnote disclosures normally included with financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to these rules and regulations. The unaudited financial statements included in this report reflect all the adjustments, consisting of normal recurring adjustments, which the Company considers necessary for a fair statement of the results of operations for the interim periods covered and for the financial condition of the Company at the date of the interim balance sheet. Results for the interim periods are not necessarily indicative of results for the full year. Certain prior-year amounts in the Company's unaudited condensed consolidated financial statements have been reclassified to conform to the current year presentation. As further discussed in Note 13, "Commitments and Contingencies," the impact of the Coronavirus Disease 2019 ("COVID-19") pandemic and the related economic, business and market disruptions continues to evolve and its future effects remain uncertain. The actual impact of these recent developments on the Company will depend on many factors, many of which are beyond management's control and knowledge. It is therefore difficult for management to assess or predict with precision the broad future effect of this health crisis on the global economy, the energy industry or the Company. During the first and second quarters of 2020, the Company recorded asset impairments and recorded severance and facility closure charges in response to these recent developments, as further discussed in Note 3, "Asset Impairments and Other Charges." As additional information becomes available, events or circumstances change and strategic operational decisions are made by management, further adjustments may be required which could have a material adverse impact on the Company's consolidated financial position, results of operations and cash flows. The preparation of condensed consolidated financial statements in conformity with GAAP requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Examples of such estimates include, but are not limited to, goodwill and other asset impairments, revenue and income recognized over time, valuation allowances recorded on deferred tax assets, reserves on inventory, allowances for doubtful accounts, and potential future adjustments related to contractual indemnification and other agreements. Actual results could materially differ from those estimates. The financial statements included in this report should be read in conjunction with the Company's audited financial statements and accompanying notes included in its Annual Report on Form 10-K for the year ended December 31, 2019.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB"), which are adopted by the Company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption. In June 2016, the FASB issued guidance on credit impairment for short-term receivables which, as amended, introduces the recognition of management's current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The Company adopted this guidance on January 1, 2020, using the optional transition method of recognizing any cumulative effect of adopting this guidance as an adjustment to the opening balance of retained earnings. The cumulative impact of the adoption of the new standard was not material to the Company's consolidated financial statements. Prior periods were not retrospectively adjusted.

Restructuring and Related Activities [Abstract]
Asset Impairments and Other Charges	Asset Impairments and Other Charges In March of 2020, the spot price of West Texas Intermediate ("WTI") crude oil declined over 50% in response to current and expected material reductions in global demand due to the global response to the COVID-19 pandemic, coupled with announcements by Saudi Arabia and Russia of plans to increase crude oil production. Following this unprecedented collapse in crude oil prices, the spot price of Brent and WTI crude oil closed at $15 and $21 per barrel, respectively, on March 31, 2020. Crude oil prices further declined in April of 2020 to record low levels, and while crude oil prices have increased to some extent since that time, they remain at depressed levels. Demand for most of the Company's products and services depends substantially on the level of capital expenditures by the oil and natural gas industry. This decline in oil prices has, and is expected to continue to, result in further near-term reductions to most of the Company's customers' drilling, completion and production activities and their related spending on products and services, particularly in the U.S. shale play regions. These conditions may also result in a material adverse impact on certain customers' liquidity and financial position, leading to further spending reductions, delays in the collection of amounts owed and in certain instances, non-payment of amounts owed. Consistent with oilfield service industry peers, the Company's stock price declined dramatically during the first quarter of 2020, with its market capitalization falling substantially below the carrying value of stockholders' equity. Following these March 2020 events, the Company immediately implemented significant cost reduction initiatives. The Company also assessed the carrying value of goodwill, long-lived and other assets based on the industry outlook regarding overall demand for and pricing of its products and services, other market considerations and the financial condition of the Company's customers. As a result of these events, actions and assessments, the Company recorded the following charges during the first quarter of 2020 (in thousands): Completion Services Drilling Services Downhole Technologies Offshore/ Pre-tax Total Tax After-tax Total Impairments of goodwill $ 127,054 $ — $ 192,502 $ 86,500 $ 406,056 $ 19,600 $ 386,456 Impairments of fixed assets — 5,198 — — 5,198 1,092 4,106 Impairments of inventories (Note 4) 8,981 — — 16,249 25,230 4,736 20,494 Severance and facility closure costs 331 217 — 112 660 139 521 The Company further reduced its workforce and closed additional facilities in the United States during the second quarter of 2020, and recorded the following charges (in thousands): Completion Services Downhole Technologies Offshore/ Manufactured Products Corporate Pre-tax Total Tax After-tax Total Impairments of fixed assets $ 2,992 $ — $ — $ — $ 2,992 $ 628 $ 2,364 Severance and facility closure costs 3,544 1,315 322 216 5,397 1,133 4,264 Goodwill The Company has three reporting units – Completion Services, Downhole Technologies and Offshore/Manufactured Products – with goodwill balances totaling $482.3 million as of December 31, 2019. Goodwill is allocated to each reporting unit from acquisitions made by the Company. In accordance with current accounting guidance, the Company does not amortize goodwill, but rather assesses goodwill for impairment annually and when an event occurs or circumstances change that indicate the carrying amounts may not be recoverable. If the carrying amount of a reporting unit exceeds its fair value, goodwill is considered impaired and an impairment loss is recorded. Given the significance of the March 2020 events described above, the Company performed a quantitative assessment of goodwill for impairment as of March 31, 2020. This interim assessment indicated that the fair value of each of the reporting units was less than their respective carrying amounts. Management utilizes, depending on circumstances, a combination of valuation methodologies including a market approach and an income approach, as well as guideline public company comparables. The valuation techniques used in the March 31, 2020 assessment were consistent with those used during the December 1, 2019 assessment, except for the Completion Services reporting unit where the income approach was used to estimate its fair value – with the market approach used only to validate the results in 2020. The fair values of each of the Company's reporting units were determined using significant unobservable inputs (Level 3 fair value measurements). This approach estimates fair value by discounting the Company's forecasts of future cash flows by a discount rate (expected return) that a market participant is expected to require. Significant assumptions and estimates used in the income approach include, among others, estimated future net annual cash flows and discount rates for each reporting unit, current and anticipated market conditions, estimated growth rates and historical data. These estimates rely upon significant management judgment, particularly given the continued uncertainties regarding the COVID-19 pandemic and its impact on activity levels and commodity prices as well as future global economic growth. Based on this quantitative assessment as of March 31, 2020, the Company concluded that goodwill recorded in the Completion Services and Downhole Technologies businesses was fully impaired while goodwill recorded in the Offshore/Manufactured Products business was partially impaired. The Company therefore recognized non-cash goodwill impairment charges totaling $406.1 million in the first quarter of 2020. These impairment charges did not impact the Company's liquidity position, debt covenants or cash flows. The discount rates used to value the Company's reporting units as of March 31, 2020 ranged between 16.8% and 18.5%. Holding all other assumptions and inputs used in the discounted cash flow analysis constant, a 50 basis point increase in the discount rate assumption for the Offshore/Manufactured Products reporting unit would have increased the goodwill impairment charge by approximately $10 million. A summary of changes in the carrying values of goodwill by reporting unit in the first six months of 2020 is presented in Note 4, "Details of Selected Balance Sheet Accounts." Long-lived Assets The Company also assesses the carrying value of long-lived assets, including property, plant and equipment, operating lease assets and other intangible assets held by each of its four reporting units. As a result of the March 2020 assessment, the Company concluded that property and equipment held by the Drilling Services reporting unit was further impaired and recognized a non-cash fixed asset impairment charge of $5.2 million in the first quarter of 2020. During the second quarter of 2020, the Company concluded that certain facilities held for sale by the Completion Services reporting unit were impaired and recognized a non-cash fixed asset impairment charge of $3.0 million to reduce the carrying value of the facilities to their estimated realizable value based on the current market environment. The Company performed a qualitative assessment of goodwill and long-lived assets at June 30, 2020 and concluded that no further impairment evaluation was required. As a result, no other impairments were recorded in the second quarter of 2020. Should, among other events and circumstances, global economic and industry conditions further deteriorate, the COVID-19 pandemic business and market disruptions worsen, the outlook for future operating results and cash flow for any of the Company's reporting units decline, income tax rates increase or regulations change, costs of equity or debt capital increase, valuations for comparable public companies or comparable acquisition valuations decrease, or management implement strategic decisions based on industry conditions, the Company may need to recognize additional impairment losses in future periods.

Details of Selected Balance Sheet Accounts	Details of Selected Balance Sheet Accounts Additional information regarding selected balance sheet accounts as of June 30, 2020 and December 31, 2019 is presented below (in thousands): June 30, December 31, Accounts receivable, net: Trade $ 128,549 $ 178,813 Unbilled revenue 20,970 28,341 Contract assets 25,636 26,034 Other 3,885 9,044 Total accounts receivable 179,040 242,232 Allowance for doubtful accounts (10,262) (8,745) $ 168,778 $ 233,487 Allowance for doubtful accounts as a percentage of total accounts receivable 6 % 4 % June 30, December 31, Deferred revenue (contract liabilities) $ 23,583 $ 17,761 For the six months ended June 30, 2020, the $0.4 million net decrease in contract assets was primarily attributable to $22.1 million transferred to accounts receivable, which was partially offset by $21.8 million in revenue recognized during the period. Deferred revenue (contract liabilities) increased by $5.8 million in 2020, primarily reflecting $16.6 million in new customer billings which were not recognized as revenue during the period, partially offset by the recognition of $10.5 million of revenue that was deferred at the beginning of the period. As of June 30, 2020 and December 31, 2019, 61% and 73%, respectively, of total accounts receivables related to revenues generated in the United States. As of June 30, 2020 and December 31, 2019, 18% and 10%, respectively, of total accounts receivables related to revenues generated in the United Kingdom. As of June 30, 2020, 13% of total accounts receivables related to revenues generated in Singapore. No other country or single customer accounted for more than 10% of the Company's total accounts receivables at these dates. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company's customers to make required payments. Determination of the collectability of amounts due from customers requires us to make judgments regarding future events and trends. Allowances for doubtful accounts are established through an assessment of the Company's portfolio on an individual customer and consolidated basis taking into account current and expected future market conditions and trends. This process consists of a thorough review of historical collection experience, current aging status of the customer accounts, and financial condition of the Company's customers as well as political and economic factors in countries of operations and other customer-specific factors. Based on a review of these factors, the Company establishes or adjusts allowances for trade and unbilled receivables as well as contract assets. If a customer receivable is deemed to be uncollectible, the receivable is charged-off against allowance for doubtful accounts. If the financial condition of the Company's customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. The following provides a summary of activity in the allowance for doubtful accounts for the six months ended June 30, 2020 and 2019 (in thousands): 2020 2019 Allowance for doubtful accounts – January 1 $ 8,745 $ 6,701 Provisions 2,549 453 Write-offs (2,184) (848) Other 1,152 (3) Allowance for doubtful accounts – June 30 10,262 6,303 June 30, December 31, Inventories, net: Finished goods and purchased products $ 106,124 $ 107,691 Work in process 23,421 21,963 Raw materials 108,372 110,719 Total inventories 237,917 240,373 Allowance for excess or obsolete inventory (39,641) (19,031) $ 198,276 $ 221,342 The Company recorded impairment charges totaling $25.2 million in the first quarter of 2020 to reduce the carrying value of inventories to their estimated net realizable value following the March 2020 decline in crude oil prices, which is expected to reduce the near-term utility of certain goods within the Offshore/Manufactured Products and Completion Services operations.

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt As of June 30, 2020 and December 31, 2019, long-term debt consisted of the following (in thousands): June 30, December 31, Revolving credit facility due January 2022 (1) $ 69,759 $ 50,534 1.50% convertible senior notes due February 2023 (2) 155,480 167,594 Promissory note 25,000 25,000 Other debt and finance lease obligations 4,877 5,041 Total debt 255,116 248,169 Less: Current portion (25,626) (25,617) Total long-term debt $ 229,490 $ 222,552 ____________________ (1) Presented net of $1.2 million and $1.4 million of unamortized debt issuance costs as of June 30, 2020 and December 31, 2019, respectively. (2) The outstanding principal amount of the 1.50% convertible senior notes was $174.6 million and $192.3 million as of June 30, 2020 and December 31, 2019, respectively. Revolving Credit Facility due January 2022 The Company's senior secured revolving credit facility (the "Revolving Credit Facility") is governed by an amended and restated credit agreement with Wells Fargo Bank, N.A., as administrative agent for the lenders party thereto, and the lenders and other financial institutions from time to time party thereto, dated as of January 30, 2018 (the "Credit Agreement"), which matures on January 30, 2022. Prior to June 17, 2020, the Revolving Credit Facility provided for $350.0 million in lender commitments, including $50.0 million available for the issuance of letters of credit. On June 17, 2020, the Company entered into an omnibus amendment to the Credit Agreement (as amended, the "Amended Credit Agreement"). Lender commitments under the Amended Credit Agreement were reduced to $200.0 million in exchange for the suspension of the financial covenants described below from July 1, 2020 through March 30, 2021. During the financial covenant suspension period, borrowing availability under the Revolving Credit Facility (as amended, the "Amended Revolving Credit Facility") will be limited to 85% of the lesser of (i) $200.0 million or (ii) a borrowing base, calculated monthly, equal to the sum of 70% of the consolidated net book value of eligible receivables and 20% of the consolidated net book value of eligible inventory (the "Borrowing Base"). As of June 30, 2020, the Company had $71.0 million of borrowings outstanding under the Amended Revolving Credit Facility and $28.4 million of outstanding letters of credit. The total amount available to be drawn as of July 1, 2020 was $37.3 million, calculated based on 85% of the current Borrowing Base less outstanding borrowings and letters of credit. Prior to June 17, 2020, amounts outstanding under the Revolving Credit Facility accrued interest at LIBOR plus a margin of 1.75% to 3.00%, or at a base rate plus a margin of 0.75% to 2.00%, in each case based on a ratio of the Company's total net funded debt to consolidated EBITDA (as defined in the Credit Agreement). The Company was also required to pay a quarterly commitment fee of 0.25% to 0.50%, based on the Company's ratio of total net funded debt to consolidated EBITDA, on the unused commitments under the Credit Agreement. Effective June 17, 2020, borrowings outstanding under the Amended Revolving Credit Facility bear interest at LIBOR plus a margin of 2.50% to 3.75%, or at a base rate plus a margin of 1.50% to 2.75%, in each case based on a ratio of the Company's total net funded debt to consolidated EBITDA. The Company must also pay a quarterly commitment fee of 0.50%, based on unused commitments under the Amended Credit Agreement. The Company expensed $0.5 million of previously deferred financing costs in the second quarter of 2020, which is included in interest expense, net, as a result of the amendment of the Credit Agreement. The Amended Credit Agreement contains customary financial covenants and restrictions. Specifically, except for the period from July 1, 2020 through March 30, 2021, the Company must maintain an interest coverage ratio, defined as the ratio of consolidated EBITDA to consolidated interest expense, of at least 3.0 to 1.0, a maximum senior secured leverage ratio, defined as the ratio of senior secured debt to consolidated EBITDA, of no greater than 2.25 to 1.0 and a total net leverage ratio, defined as the ratio of total net funded debt to consolidated EBITDA, of no greater than 3.75 to 1.0. The various components used in the calculation of these ratios are defined in the Amended Credit Agreement. Consolidated EBITDA and consolidated interest expense, as defined, exclude non-cash goodwill and fixed asset impairment charges, gains or losses on the extinguishment of debt, debt discount amortization, stock-based compensation expense and other non-cash charges. Borrowings under the Amended Credit Agreement are secured by a pledge of substantially all of the Company's assets and the assets of its domestic subsidiaries. The Company's obligations under the Amended Credit Agreement are guaranteed by its significant domestic subsidiaries. The Amended Credit Agreement also contains negative covenants that limit the Company's ability to accumulate cash in excess of $45.0 million in the United States, borrow additional funds, encumber assets, pay dividends, sell assets, repurchase shares of common stock and enter into other significant transactions. Under the Amended Credit Agreement, the occurrence of specified change of control events involving the Company would constitute an event of default that would permit the banks to, among other things, accelerate the maturity of the facility and cause it to become immediately due and payable in full. As of June 30, 2020, the Company was in compliance with its debt covenants under the Amended Credit Agreement. 1.50% Convertible Senior Notes due February 2023 On January 30, 2018, the Company issued $200 million aggregate principal amount of its 1.50% convertible senior notes due 2023 (the "Notes") pursuant to an indenture, dated as of January 30, 2018 (the "Indenture"), between the Company and Wells Fargo Bank, National Association, as trustee. During the second quarter of 2020, the Company purchased $12.0 million principal amount of the outstanding Notes for $5.9 million in cash. The net carrying amount of the liability component of these Notes totaled $10.6 million. In connection with extinguishment of these Notes, the Company recognized a non-cash gain of $4.8 million during the second quarter of 2020, which is included within other income, net. During the first quarter of 2020, the Company purchased $5.7 million principal amount of the outstanding Notes for $4.7 million in cash, which approximated the net carrying amount of the related liability. Since September 2019, the Company has purchased $25.4 million principal amount of the outstanding notes for $17.3 million in cash. The initial carrying amount of the Notes recorded in the consolidated balance sheet was less than the $200 million principal amount of the Notes, in accordance with applicable accounting principles, reflective of the estimated fair value of a similar debt instrument that does not have a conversion feature. The Company recorded the value of the conversion feature as a debt discount, which is amortized as interest expense over the term of the Notes, with a similar amount allocated to additional paid-in capital. As a result of this amortization, interest expense recognized on the Notes for accounting purposes, reflecting an effective interest rate of approximately 6%, is greater than cash interest the Company is obligated to pay. Reported interest expense associated with the Notes for the three and six months ended June 30, 2020 was $2.4 million and $4.9 million, respectively, while the related contractual cash interest expense totaled $0.7 million and $1.4 million, respectively. Reported interest expense associated with the Notes for the three and six months ended June 30, 2019 was $2.5 million and $5.1 million, respectively, while the related contractual cash interest expense totaled $0.8 million and $1.5 million, respectively. The following table presents the carrying amount of the Notes in the consolidated balance sheets as of June 30, 2020 and December 31, 2019 (in thousands): June 30, December 31, Principal amount of the liability component $ 174,569 $ 192,250 Less: Unamortized discount 16,656 21,544 Less: Unamortized issuance costs 2,433 3,112 Net carrying amount of the liability component $ 155,480 $ 167,594 Net carrying amount of the equity component $ 25,683 $ 25,683 The Notes bear interest at a rate of 1.50% per year until maturity. Interest is payable semi-annually in arrears on February 15 and August 15 of each year. In addition, additional interest and special interest may accrue on the Notes under certain circumstances as described in the Indenture. The Notes will mature on February 15, 2023, unless earlier repurchased, redeemed or converted. The initial conversion rate is 22.2748 shares of the Company's common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $44.89 per share of common stock). The conversion rate, and thus the conversion price, may be adjusted under certain circumstances as described in the Indenture. The Company's intent is to repay the principal amount of the Notes in cash and the conversion feature in shares of the Company's common stock. Noteholders may convert their Notes, at their option, only in the following circumstances: (1) if the last reported sale price per share of the Company's common stock exceeds 130% of the conversion price for each of at least 20 trading days during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the "measurement period") in which the trading price per $1,000 principal amount of the Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company's common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company's common stock, as described in the Indenture; or (4) if the Company calls the Notes for redemption, or at any time from, and including, November 15, 2022 until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of common stock or a combination of cash and shares of common stock, at the Company's election, based on the applicable conversion rate(s). If the Company elects to deliver cash or a combination of cash and shares of common stock, then the consideration due upon conversion will be based on a defined observation period. The Notes will be redeemable, in whole or in part, at the Company's option at any time, and from time to time, on or after February 15, 2021, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of common stock exceeds 130% of the conversion price on each of at least 20 trading days during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice. If specified change in control events involving the Company as defined in the Indenture occur, then noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest. Additionally, the Indenture contains certain events of default, including certain defaults by the Company with respect to other indebtedness of at least $40.0 million. As of June 30, 2020, none of the conditions allowing holders of the Notes to convert, or requiring the Company to repurchase the Notes, had been met. Promissory Note In connection with the 2018 acquisition of GEODynamics, Inc. ("GEODynamics"), the Company issued a $25.0 million promissory note that bears interest at 2.50% per annum and was scheduled to mature on July 12, 2019. Payments due under the promissory note are subject to set off, in part or in full, against certain indemnification claims related to matters occurring prior to the Company's acquisition of GEODynamics. As more fully described in Note 13, "Commitments and Contingencies," the Company has provided notice to and asserted indemnification claims against the seller of GEODynamics. As a result, the maturity date of the note is extended until these indemnity claims are resolved. The Company expects that the amount ultimately paid in respect of such note to be reduced by these indemnification claims.

Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive LossAccumulated other comprehensive loss, reported as a component of stockholders' equity, increased from $67.7 million at December 31, 2019 to $83.8 million at June 30, 2020, due to changes in currency exchange rates. Accumulated other comprehensive loss is primarily related to fluctuations in the currency exchange rates compared to the U.S. dollar which are used to translate certain of the international operations of the Company's reportable segments. For the six months ended June 30, 2020 and 2019, currency translation adjustments recognized as a component of other comprehensive income were primarily attributable to the United Kingdom and Brazil. As of June 30, 2020, the exchange rate for the British pound and the Brazilian real compared to the U.S. dollar weakened by 6% and 27%, respectively, compared to the exchange rate at December 31, 2019, contributing to other comprehensive loss of $16.0 million reported for the six months ended June 30, 2020. During the first six months of 2019, the exchange rates did not materially change.

Share-based Payment Arrangement [Abstract]
Long-Term Incentive Compensation	Long-Term Incentive Compensation The following table presents a summary of activity for stock options, service-based restricted stock awards and performance-based stock unit awards for the six months ended June 30, 2020 (in thousands): Stock Options Service-based Restricted Stock Performance-based Stock Units Outstanding – December 31, 2019 636 1,064 248 Granted — 684 181 Vested/Exercised — (529) (125) Forfeited (50) (55) — Outstanding – June 30, 2020 586 1,164 304 Weighted average grant date fair value (2020 awards) $ — $ 10.03 $ 11.15 The restricted stock program consists of a combination of service-based restricted stock and performance-based stock units. Service-based restricted stock awards generally vest on a straight-line basis over their term, which is generally three years. Performance-based restricted stock awards generally vest at the end of a three-year period, with the number of shares ultimately issued under the program dependent upon achievement of predefined specific performance measures. In the event the predefined targets are exceeded for any performance-based award, additional shares up to a maximum of 200% of the target award may be granted. Conversely, if actual performance falls below the predefined target, the number of shares vested is reduced. If the actual performance falls below the threshold performance level, no restricted shares will vest. The performance measure for outstanding awards is the Company's EBITDA growth rate over a three-year period. During the first quarters of 2020 and 2019, the Company issued conditional long-term cash incentive awards ("Cash Awards") of approximately $2.0 million and $1.4 million, respectively, with the ultimate dollar amount to be awarded ranging from zero to a maximum of $4.0 million for the 2020 Cash Award and from zero to a maximum of $2.7 million for the 2019 Cash Award. The performance measure for these Cash Awards is relative total stockholder return compared to a peer group of companies measured over a three-year period. The ultimate dollar amount to be awarded for the 2020 and 2019 Cash Awards is limited to their targeted award value ($2.0 million and $1.4 million, respectively) if the Company's total stockholder return is negative over the performance period. The obligation related to the Cash Awards is classified as a liability and recognized over the vesting period. Stock-based compensation expense recognized during the three and six months ended June 30, 2020 totaled $2.1 million and $3.3 million, respectively. Stock-based compensation expense recognized during the three and six months ended June 30, 2019 totaled $4.2 million and $8.6 million, respectively. As of June 30, 2020, there was $13.6 million of pre-tax compensation costs related to service-based and performance-based stock awards, which will be recognized in future periods as vesting conditions are satisfied.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax benefit for the three and six month periods ended June 30, 2020 was calculated using a discrete approach. This methodology was used because changes in the Company's results of operations and non-deductible expenses can materially impact the estimated annual effective tax rate. For the three months ended June 30, 2020, the Company's income tax benefit was $6.9 million on a pre-tax loss of $31.5 million, which includes certain non-deductible expenses. This compares to an income tax benefit of $0.3 million on a pre-tax loss of $10.0 million, which includes certain non-deductible expenses, for the three months ended June 30, 2019. For the six months ended June 30, 2020, the Company's income tax benefit was $46.4 million on a pre-tax loss of $476.1 million, which included non-cash goodwill charges (approximately $313.1 million) and other expenses that are not deductible for income tax purposes. The impact of these non-deductible expenses was partially offset by a $14.8 million discrete tax benefit related to the carryback of U.S. net operating losses under the CARES Act (discussed below). This compares to an income tax benefit of $0.5 million on a pre-tax loss of $24.9 million, which includes certain non-deductible expenses, for the six months ended June 30, 2019. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was signed into law. In accordance with the recently established rules and procedures under the CARES Act, the Company has filed carryback claims regarding U.S. net operating losses generated in 2018 and 2019. Prior to the enactment of the CARES Act, such tax losses could only be carried forward. The Company expects to receive refunds related to these carryback claims in 2020 of approximately $42.1 million, which are classified as income taxes receivable in the consolidated balance sheet as of June 30, 2020.

Segments and Related Information	Segments and Related Information The Company operates through three reportable segments: Well Site Services, Downhole Technologies and Offshore/Manufactured Products. The Company's reportable segments represent strategic business units that generally offer different products and services.

The balance of revenues for the respective periods relates to products and services transferred to customers at a point in time. As of June 30, 2020, the Company had $151 million of remaining backlog related to contracts with an original expected duration of greater than one year. Approximately 35% of this remaining backlog is expected to be recognized as revenue over the remaining six months of 2020, with an additional 33% in 2021 and the balance thereafter.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesThe impact of the recent COVID-19 pandemic and related economic, business and market disruptions continues to evolve and its future effects remain uncertain. The most direct and immediate impact that the Company has experienced and expects to continue to experience from the COVID-19 pandemic is decreased demand for its products and services due to lower activity levels by its customers resulting from the precipitous decline in crude oil prices. The overall impact of the pandemic and oil price collapse on the Company and its customers will depend on many factors, many of which are beyond management's control and knowledge. In response to public health concerns related to COVID-19, many federal, state, local and other authorities around the world have imposed mandatory regulations directing individuals to stay at home and limiting their ability to travel domestically or internationally. In certain cases, when travel is permitted, a multi-week quarantine period is required before an individual can work in the area. Additionally, rules and regulations regarding employer responsibilities continue to be promulgated. Facility closures, quarantines, travel restrictions, and possible future workforce shortages may, among numerous other impacts, result in delays by the Company in fulfilling its existing contractual obligations to its customers, which could result in adverse financial consequences. Additionally, the Company procures a variety of raw materials and component products, including steel, in the manufacture of its products from companies which may be impacted similar challenges. The Company continues to monitor the effect of COVID-19 on its employees, customers, critical suppliers and other stakeholders. The ultimate magnitude and duration of the COVID-19 pandemic, resulting governmental restrictions placing limitations on the mobility and ability to work of the worldwide population, and the related impact on crude oil prices and the U.S. and global economy and capital markets remains uncertain. Following the Company's acquisition of GEODynamics in January 2018, the Company determined that certain steel products historically imported by GEODynamics from China for use in its manufacturing process may potentially be subject to anti-dumping and countervailing duties based on recent clarifications/decisions rendered by the U.S. Department of Commerce and the U.S. Court of International Trade. Following these findings, the Company commenced an internal review of this matter and ceased further purchases of these potentially affected Chinese products. As part of the Company's internal review, the Company engaged trade counsel and decided to voluntarily disclose this matter to U.S. Customs and Border Protection in September 2018. In connection with the acquisition of GEODynamics, the seller agreed to indemnify and hold the Company harmless against certain claims related to matters such as this, and the Company has provided notice to and asserted indemnification claims against the seller. Additionally, the Company is able to set-off payments due under the $25.0 million promissory note (see Note 6, "Long-term Debt") issued to the seller of GEODynamics in respect of indemnification claims. Such note was scheduled to mature on July 12, 2019, but, because the Company has provided notice to and asserted indemnification claims, the maturity date of the note is extended until the resolution of such claim. The Company expects that the amount ultimately paid in respect of such note will be reduced as a result of these indemnification claims. Additionally, in the ordinary course of conducting its business, the Company becomes involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state and local levels. The Company is a party to various pending or threatened claims, lawsuits and administrative proceedings seeking damages or other remedies concerning its commercial operations, products, employees and other matters, including occasional claims by individuals alleging exposure to hazardous materials as a result of the Company's products or operations. Some of these claims relate to matters occurring prior to the acquisition of businesses, and some relate to businesses the Company has sold. In certain cases, the Company is entitled to indemnification from the sellers of businesses and, in other cases, the Company has indemnified the buyers of businesses. Although the Company can give no assurance about the outcome of pending legal and administrative proceedings and the effect such outcomes may have on the Company, management believes that any ultimate liability resulting from the outcome of such proceedings, to the extent not otherwise provided for or covered by indemnity or insurance, will not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions GEODynamics historically leased certain land and facilities from an equity holder who was employed by the Company through March 31, 2020. In connection with the acquisition of GEODynamics, the Company assumed these leases. Rent expense related to leases with this former employee for the three months ended March 31, 2020 totaled $44 thousand. Rent expense related to leases with this former employee for the three and six months ended June 30, 2019 totaled $44 thousand and $69 thousand, respectively.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB"), which are adopted by the Company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption. In June 2016, the FASB issued guidance on credit impairment for short-term receivables which, as amended, introduces the recognition of management's current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The Company adopted this guidance on January 1, 2020, using the optional transition method of recognizing any cumulative effect of adopting this guidance as an adjustment to the opening balance of retained earnings. The cumulative impact of the adoption of the new standard was not material to the Company's consolidated financial statements. Prior periods were not retrospectively adjusted.
