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 (the "Company") have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial information. Certain information in footnote disclosures normally included with financial statements prepared in accordance with 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 developments on the Company will depend on numerous 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 2020 and the first nine months of 2021, the Company recorded asset impairments, severance and restructuring charges in response to these developments as further discussed in Note 3, "Asset Impairments and Other Restructuring Items." 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 long-lived asset impairments, revenue and income recognized over time, valuation allowances recorded on deferred tax assets, reserves on inventory, allowances for doubtful accounts, settlement of litigation 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, 2020.

Accounting Policies [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 August 2020, the FASB issued updated guidance to simplify the accounting for convertible instruments and contracts in an entity's own equity (referred to as "ASU 2020-06"). This guidance eliminated the requirement that the carrying value of convertible debt instruments, such as the Company's 1.50% convertible senior notes due 2023 (the "2023 Notes"), be allocated between debt and equity components. As permitted under the standard, the Company adopted the guidance on January 1, 2021, using the modified retrospective transition method. Adoption of the standard resulted in a $12.2 million increase in the net carrying value of the 2023 Notes, a $2.7 million decrease in deferred income taxes and a $9.5 million net decrease in stockholders' equity. The effective interest rate associated with the 2023 Notes after adoption decreased from approximately 6% to approximately 2%, which compares to the contractual interest rate of 1.50%. As further discussed in Note 5, "Long-term Debt," the Company issued $135.0 million principal amount of its 4.75% convertible senior notes due 2026 (the "2026 Notes") on March 19, 2021, which have been accounted for in accordance with the provisions of ASU 2020-06.

Asset Impairments and Other Restructuring Items	Sep. 30, 2021
Restructuring and Related Activities [Abstract]
Asset Impairments and Other Restructuring Items	Asset Impairments and Other Restructuring Items In March of 2020, the spot price of West Texas Intermediate ("WTI") crude oil declined over 50% in response to actual and forecasted reductions in global demand for crude oil due to the COVID-19 pandemic, coupled with announcements by Saudi Arabia and Russia of plans to increase crude oil production. 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, and these conditions caused rapid reductions to most of the Company's customers' drilling, completion and production activities and their related spending on products and services, particularly those supporting activities in the U.S. shale play regions. While the prices of and demand for crude oil have increased significantly since reaching record low levels in April 2020, uncertainty remains regarding the timing of demand recovery to pre-COVID-19 levels and operators' willingness to invest in U.S. land-based drilling, completion and production activities given regulatory pressures around environmental, social and governance considerations. 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): Offshore/ Downhole Technologies Well Site Services Corporate Pre-tax Total Tax After-tax Total First quarter 2020 Impairments of: Goodwill $ 86,500 $ 192,502 $ 127,054 $ — $ 406,056 $ 19,600 $ 386,456 Fixed assets — — 5,198 — 5,198 1,092 4,106 Inventories (Note 4) 16,249 — 8,981 — 25,230 4,736 20,494 Severance and restructuring costs 112 — 548 — 660 139 521 During the second and third quarters of 2020, the Company further reduced its workforce and closed additional facilities in the United States and continued to assess the carrying value of its assets based on the industry outlook regarding demand for and pricing of its products and services, and recorded the following charges (in thousands): Offshore/ Manufactured Products Downhole Technologies Well Site Services Corporate Pre-tax Total Tax After-tax Total Second quarter 2020 Impairments of fixed assets $ — $ — $ 2,992 $ — $ 2,992 $ 628 $ 2,364 Severance and restructuring costs 322 1,315 3,544 216 5,397 1,133 4,264 Third quarter 2020 Impairments of inventories (Note 4) $ — $ 5,921 $ — $ — $ 5,921 $ 1,243 $ 4,678 Severance and restructuring costs 288 — — — 288 60 228 During the first nine months of 2021, the Company continued its restructuring efforts, closed additional facilities in the United States and continued to assess the carrying value of its assets based on management actions and the industry outlook regarding demand for and pricing of its products and services, and recorded the following charges (in thousands): Offshore/ Manufactured Products Downhole Technologies Well Site Services Corporate Pre-tax Total Tax After-tax Total First quarter 2021 Impairments of fixed assets $ — $ — $ 650 $ — $ 650 $ 137 $ 513 Severance and restructuring costs 282 275 1,306 1,555 3,418 717 2,701 Second quarter 2021 Impairments of operating lease assets $ — $ — $ 2,794 $ — $ 2,794 $ 587 $ 2,207 Severance and restructuring costs (1) — 203 2,351 — 2,554 536 2,018 Third quarter 2021 Impairment of inventories (Note 4) $ — $ 2,113 $ — $ — $ 2,113 $ 444 $ 1,669 Severance and restructuring costs 256 129 352 — 737 154 583 ____________________ (1) Includes recognition of $1.9 million in additional lease-related liabilities associated with the exit of a long-term lease supporting the Well Site Services segment. Additionally, during the three and nine months ended September 30, 2021, the Company recognized $1.2 million and $8.8 million, respectively, in aggregate reductions to payroll tax expense (within cost of revenues and selling, general and administrative expense) as part of the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") employee retention credit program. The Company continues to evaluate any and all benefits potentially available to it under the CARES Act. Goodwill Goodwill is allocated to each reporting unit based on acquisitions made by the Company and is assessed 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. The Company had three reporting units – Offshore/Manufactured Products, Downhole Technologies and Well Site Services – whose goodwill balances totaled $482.3 million as of December 31, 2019. 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 due to, among other factors, the significant decline in the Company's stock price (and that of its peers) and reduced growth rate expectations given weak energy market conditions resulting from the demand destruction caused by the global response to the COVID-19 pandemic. In addition, the estimated returns required by market participants increased materially in the Company's March 31, 2020 assessment from the assessment performed as of December 1, 2019, resulting in higher discount rates used in the discounted cash flow analysis. 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 fair values of the Company's reporting units were determined using significant unobservable inputs (Level 3 fair value measurements). Based on this quantitative assessment as of March 31, 2020, the Company concluded that goodwill recorded in the Downhole Technologies and Well Site Services segments was fully impaired while goodwill recorded in the Offshore/Manufactured Products segment was partially impaired. The Company therefore recognized non-cash goodwill impairment charges totaling $406.1 million in the first quarter of 2020, as presented in further detail in the table above. The Company performed its annual quantitative assessment of goodwill as of December 1, 2020, which indicated that the fair value of the Offshore/Manufactured Products segment was greater than its carrying amount and no additional provision for impairment was required. The Company's remaining goodwill within the segment totaled approximately $76.5 million as of September 30, 2021 and December 31, 2020. 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 segments (reporting units). As a result of the March 2020 assessment, the Company concluded that certain drilling-related property and equipment held by the Well Site Services segment was impaired and recognized a non-cash fixed asset impairment charge of $5.2 million in the first quarter of 2020. During the nine months ended September 30, 2021, the Well Site Services segment recognized non-cash fixed and operating lease asset impairment charges of $3.4 million associated with the closure of additional facilities coupled with other management actions. During the nine months ended September 30, 2021, the segment also recorded an additional $1.9 million charge associated with the exit of a leased facility. Should, among other events and circumstances, global economic and industry conditions deteriorate, the COVID-19 pandemic business and market disruptions continue, the outlook for future operating results and cash flow for any of the Company's segments decline, income tax rates increase or regulations change, climate and environmental 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 September 30, 2021 and December 31, 2020 is presented below (in thousands): September 30, December 31, Accounts receivable, net: Trade $ 112,077 $ 109,294 Unbilled revenue 21,523 23,173 Contract assets 22,428 35,870 Other 11,672 3,102 Total accounts receivable 167,700 171,439 Allowance for doubtful accounts (6,260) (8,304) $ 161,440 $ 163,135 Allowance for doubtful accounts as a percentage of total accounts receivable 4 % 5 % September 30, December 31, Deferred revenue (contract liabilities) $ 42,512 $ 43,384 As of September 30, 2021, accounts receivable, net in the United States and the United Kingdom represented 77% and 12%, respectively, of the total. No other country or single customer accounted for more than 10% of the Company's total accounts receivable as of September 30, 2021. For the nine months ended September 30, 2021, the $13.4 million net decrease in contract assets was primarily attributable to $34.6 million transferred to accounts receivable, which was partially offset by $21.1 million in revenue recognized during the period. Deferred revenue (contract liabilities) decreased by $0.9 million in the first nine months of 2021, primarily reflecting the recognition of $6.1 million of revenue that was deferred at the beginning of the period, partially offset by $5.3 million in new customer billings which were not recognized as revenue during the period. The following provides a summary of activity in the allowance for doubtful accounts for the nine months ended September 30, 2021 and 2020 (in thousands): Nine Months Ended September 30, 2021 2020 Allowance for doubtful accounts – January 1 $ 8,304 $ 8,745 Provisions 20 2,787 Write-offs (2,200) (2,490) Other 136 1,158 Allowance for doubtful accounts – September 30 $ 6,260 $ 10,200 September 30, December 31, Inventories, net: Finished goods and purchased products $ 90,558 $ 88,634 Work in process 33,852 27,063 Raw materials 93,779 95,410 Total inventories 218,189 211,107 Allowance for excess or obsolete inventory (40,111) (40,731) $ 178,078 $ 170,376 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 reduced the near-term utility of certain goods within the Offshore/Manufactured Products and Well Site Services segments. During the third quarter of 2020, the Company recorded an impairment charge of $5.9 million to reduce the carrying value of inventories within the Downhole Technologies segment to their estimated net realizable value based on changes in expectations regarding the near-term utility, customer demand and market pricing of certain goods. The Company recorded an impairment charge of $2.1 million in the third quarter of 2021 to reduce the carrying value of inventories within the Downhole Technologies segment to their estimated net realizable value based primarily on management's decision to exit a product offering.

Long-term Debt	Sep. 30, 2021
Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt As of September 30, 2021 and December 31, 2020, long-term debt consisted of the following (in thousands): September 30, December 31, Revolving credit facilities (1) $ — $ 18,408 2026 Notes (2) 131,071 — 2023 Notes (3) 25,765 143,242 Promissory note 17,534 17,095 Other debt and finance lease obligations 4,298 4,792 Total debt 178,668 183,537 Less: Current portion (18,234) (17,778) Total long-term debt $ 160,434 $ 165,759 ____________________ (1) Presented net of $0.6 million of unamortized deferred financing costs as of December 31, 2020. Unamortized deferred financing costs of $2.9 million as of September 30, 2021 are presented in Other noncurrent assets. (2) The outstanding principal amount of the 2026 Notes was $135.0 million as of September 30, 2021. (3) The outstanding principal amount of the 2023 Notes was $26.0 million and $157.4 million as of September 30, 2021 and December 31, 2020, respectively. Revolving Credit Facilities ABL Facility On February 10, 2021, the Company entered into a senior secured credit facility with certain lenders, which provides for a $125.0 million asset-based revolving credit facility (the "ABL Facility") under which credit availability is subject to a borrowing base calculation. Concurrent with entering into this facility, the Company's former senior secured revolving credit facility (discussed below) was terminated. On March 16, 2021, the Company entered into an amendment to the ABL Facility that permitted the Company to incur the indebtedness represented by the 2026 Notes. The ABL Facility is governed by a credit agreement, as amended, with Wells Fargo Bank, National Association, as administrative agent and the lenders and other financial institutions from time to time party thereto (the "ABL Agreement"). The ABL Agreement matures on February 10, 2025 with a springing maturity 91 days prior to the maturity of any outstanding indebtedness with a principal amount in excess of $17.5 million (excluding the unsecured promissory note discussed below). The ABL Agreement provides funding based on a borrowing base calculation that includes eligible U.S. customer accounts receivable and inventory and provides for a $50.0 million sub-limit for the issuance of letters of credit. Borrowings under the ABL Agreement are secured by a pledge of substantially all of the Company's domestic assets (other than real property) and the stock of certain foreign subsidiaries. Borrowings under the ABL Agreement bear interest at a rate equal to the London Interbank Offered Rate ("LIBOR") plus a margin of 2.75% to 3.25% and subject to a LIBOR floor rate of 0.50%, or at a base rate plus a margin of 1.75% to 2.25%, in each case based on average borrowing availability. Quarterly, the Company must also pay a commitment fee of 0.375% to 0.50% per annum, based on unused commitments under the ABL Agreement. The ABL Agreement places restrictions on the Company's ability to incur additional indebtedness, grant liens on assets, pay dividends or make distributions on equity interests, dispose of assets, make investments, repay other indebtedness (including the 2023 Notes and the 2026 Notes), engage in mergers, and other matters, in each case, subject to certain exceptions. The ABL Agreement contains customary default provisions, which, if triggered, could result in acceleration of all amounts then outstanding. The ABL Agreement also requires the Company to satisfy and maintain a fixed charge coverage ratio of not less than 1.0 to 1.0 for specified periods of time: in the event that availability under the ABL Agreement is less than the greater of 15% of the borrowing base and $14.1 million; to complete certain specified transactions; or if an event of default has occurred and is continuing. As of September 30, 2021, the Company had $16.5 million of outstanding letters of credit, but no borrowings outstanding under the ABL Agreement. The total amount available to be drawn as of September 30, 2021 was $61.4 million, calculated based on the current borrowing base less outstanding borrowings, if any, and letters of credit. As of September 30, 2021, the Company was in compliance with its debt covenants under the ABL Agreement. Former Revolving Credit Facility Until its termination on February 10, 2021, the Company's former senior secured revolving credit facility was governed by a credit agreement which was scheduled to mature on January 30, 2022. On June 17, 2020, the Company entered into an omnibus amendment to the credit agreement, under which lender commitments were reduced in exchange for the suspension of certain financial covenants through March 30, 2021. The following provides a summary of the more significant provisions of the Company's former revolving credit facility. Prior to June 17, 2020 From June 17, 2020 to February 10, 2021 Lender commitments $350 million $200 million Interest rate on outstanding borrowings (1) : LIBOR based borrowings LIBOR plus a margin of 1.75% to 3.00% LIBOR plus a margin of 2.50% to 3.75% Base-rate based borrowings Base rate plus a margin of 0.75% to 2.00% Base rate plus a margin of 1.50% to 2.75% Commitment fees (2) 0.25% to 0.50% 0.375% to 0.50% ____________________ (1) Based on the ratio of the Company's total net funded debt to consolidated EBITDA. (2) Based on unused commitments under the credit agreement. 2026 Notes On March 19, 2021, the Company issued $135.0 million aggregate principal amount of the 2026 Notes pursuant to an indenture, dated as of March 19, 2021 (the "2026 Indenture"), between the Company and Wells Fargo Bank, National Association, as trustee. Net proceeds from the 2026 Notes offering, after deducting issuance costs, totaled $130.6 million. The Company used $120.0 million of the cash proceeds to purchase $125.0 million principal amount of the outstanding 2023 Notes at a discount, with the balance added to cash on-hand. The 2026 Notes bear interest at a rate of 4.75% per year and will mature on April 1, 2026, unless earlier repurchased, redeemed or converted. Interest is payable semi-annually in arrears on April 1 and October 1 of each year. Additional interest and special interest may accrue on the 2026 Notes under certain circumstances as described in the 2026 Indenture. The initial conversion rate is 95.3516 shares of the Company's common stock per $1,000 principal amount of 2026 Notes (equivalent to an initial conversion price of approximately $10.49 per share of common stock). The conversion rate, and thus the conversion price, may be adjusted under certain circumstances as described in the 2026 Indenture. The Company's intent is to repay the principal amount of the 2026 Notes in cash and settle the conversion feature in shares of the Company's common stock. Noteholders may convert their 2026 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 2026 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 2026 Indenture; or (4) if the Company calls the 2026 Notes for redemption, or at any time from, and including, January 1, 2026 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 2026 Notes will be redeemable, in whole or in part, at the Company's option on or after April 6, 2024, at a cash redemption price equal to the principal amount of the 2026 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 2026 Indenture occur, then noteholders may require the Company to repurchase their 2026 Notes at a cash repurchase price equal to the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid interest. Additionally, the 2026 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 September 30, 2021, none of the conditions allowing holders of the 2026 Notes to convert, or requiring the Company to repurchase the 2026 Notes, had been met. 2023 Notes On January 30, 2018, the Company issued $200.0 million aggregate principal amount of the 2023 Notes, pursuant to an indenture, dated as of January 30, 2018 (the "2023 Indenture"), between the Company and Wells Fargo Bank, National Association, as trustee. The 2023 Notes bear interest at a rate of 1.50% per year and 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 2023 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 2023 Indenture. The Company's intent is to repay the principal amount of the Notes in cash and settle the conversion feature in shares of the Company's common stock. The initial carrying amount of the 2023 Notes recorded in the consolidated balance sheet was less than their principal amount, in accordance with then-applicable accounting principles, reflective of the estimated fair value of a similar debt instrument that did not have a conversion feature. The Company recorded the value of the conversion feature as a debt discount, which was amortized as interest expense over the term of the 2023 Notes, with a similar amount allocated to additional paid-in capital. As a result of this amortization, prior to the Company's adoption of the ASU 2020-06 revision to accounting guidance for convertible instruments effective January 1, 2021, the interest expense recognized on the 2023 Notes for accounting purposes was based on an effective interest rate of approximately 6%, which was greater than the cash interest the Company is obligated to pay. See Note 2, "Recent Accounting Pronouncement," for discussion of ASU 2020-06, which changed the Company's method of accounting for the 2023 Notes upon adoption. The following table provides details with respect to the carrying amount of the 2023 Notes in the consolidated balance sheets as of September 30, 2021 and December 31, 2020 (in thousands): September 30, December 31, Principal amount of the liability component $ 25,969 $ 157,369 Less: Unamortized discount — 12,308 Less: Unamortized issuance costs 204 1,819 Net carrying amount of the liability component $ 25,765 $ 143,242 Net carrying amount of the equity component n.a. $ 25,683 The following table presents the Company's purchases of outstanding 2023 Notes during the three and nine months ended September 30, 2021 and 2020, with non-cash gains included within other income, net (in thousands): Principal Amount Carrying Value of Liability Cash Paid Non-cash Gains Recognized Three Months Ended September 30, 2021 $ — $ — $ — $ — 2020 17,200 15,425 9,483 5,942 Nine Months Ended September 30, 2021 $ 131,400 $ 129,974 $ 125,952 $ 4,022 2020 34,881 30,799 20,078 10,721 Since December 31, 2018, the Company has purchased a cumulative $174.0 million principal amount of the outstanding 2023 Notes for $152.8 million in cash. Promissory Note In connection with the 2018 acquisition of GEODynamics (the "GEODynamics Acquisition"), 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 full or in part, against certain indemnification claims related to matters occurring prior to the GEODynamics Acquisition. The Company has provided notice to and asserted indemnification claims against the seller of GEODynamics (the "Seller"), and the Seller has filed a breach of contract suit against the Company and one of its wholly-owned subsidiaries alleging that payments due under the promissory note are required to be, but have not been, repaid in accordance with the terms of such note. The Company has incurred settlement costs and expenses of $7.5 million related to such indemnification claims, and believes that the maturity date of such note is extended until the resolution of such indemnity claims and that it is permitted to set-off the principal amount owed by the amount of such costs and expenses. Accordingly, the Company has reduced the carrying amount of such note in the consolidated balance sheet to $17.5 million as of September 30, 2021, which is its current best estimate of what is owed after set-off for such indemnification matters. See Note 13, "Commitments and Contingencies."

Equity [Abstract]
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss Accumulated other comprehensive loss, reported as a component of stockholders' equity, increased from $71.4 million at December 31, 2020 to $75.6 million at September 30, 2021, due to changes in currency exchange rates. Accumulated other comprehensive loss is primarily related to fluctuations in currency exchange rates compared to the U.S. dollar as used to translate certain of the international operations of the Company's operating segments. For the nine months ended September 30, 2021 and 2020, currency translation adjustments recognized as a component of other comprehensive loss were primarily attributable to the United Kingdom and Brazil. As of September 30, 2021, the exchange rate for the British pound and the Brazilian real compared to the U.S. dollar weakened by 1% and 5%, respectively, compared to the exchange rates at December 31, 2020, contributing to other comprehensive loss of $4.2 million reported for the nine months ended September 30, 2021. During the first nine months of 2020, the exchange rate for the British pound and the Brazilian real compared to the U.S. dollar weakened by 2% and 29%, respectively, compared to the exchange rate at December 31, 2019, contributing to other comprehensive loss of $12.7 million reported for the nine months ended September 30, 2020.

This compares to an income tax benefit of $7.7 million on a pre-tax loss of $27.6 million, which included certain non-deductible expenses, for the three months ended September 30, 2020. For the nine months ended September 30, 2021, the Company's income tax benefit was $9.1 million on a pre-tax loss of $53.2 million, which included certain non-deductible expenses. This compares to an income tax benefit of $54.1 million on a pre-tax loss of $503.7 million, which included non-cash goodwill charges (approximately $313.1 million) and other expenses that are not deductible for income tax purposes, for the nine months ended September 30, 2020. The impact of these non-deductible expenses in 2020 was partially offset by a $16.4 million discrete tax benefit related to the carryback of U.S. net operating losses under the CARES Act.

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 nine months ended September 30, 2021 (in thousands): Stock Options Service-based Restricted Stock Performance-based Stock Units Outstanding – December 31, 2020 530 1,087 287 Granted — 598 245 Vested — (633) (70) Forfeited (142) (59) (42) Outstanding – September 30, 2021 388 993 420 Weighted average grant date fair value (2021 awards) $ — $ 6.78 $ 6.84 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 a term of three years. Performance-based 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 objectives. The performance objective for performance-based awards granted in 2021 is the Company's cumulative EBITDA over a three-year period. The performance objective for outstanding awards granted in 2020 and 2019 is the Company's EBITDA growth rate over a three-year period. 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. During the first quarters of 2021 and 2020, the Company issued conditional long-term cash incentive awards ("Cash Awards") of $1.5 million and $1.5 million (adjusted for forfeitures), respectively, with the ultimate dollar amount to be awarded ranging from zero to a maximum of $3.1 million for the 2021 Cash Award and from zero to a maximum of $3.0 million for the 2020 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 2021 and 2020 Cash Awards is limited to their targeted award value ($1.5 million) if the Company's total stockholder return is negative over the performance period.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies During the first nine months of 2021, the distribution of COVID-19 vaccines progressed and many government-imposed restrictions were relaxed or rescinded. However, the effect of the COVID-19 pandemic and related economic, business and market disruptions remains uncertain. The most direct and immediate impacts that the Company continues to experience is decreased demand for and pricing of its products and services due to lower activity levels by its customers resulting from the reduction in the demand for crude oil, market pressures driving increased capital discipline and, to a lesser extent, supply chain disruptions. While the prices of and demand for crude oil have recovered from the lows seen in the initial stages of the pandemic, further outbreaks or the emergence of new strains of the COVID-19 virus could result in the reimposition of domestic and international regulations directing individuals to stay at home, limiting travel, requiring facility closures and imposing quarantines. Widespread implementation of these or similar restrictions could result in reductions in the prices of and demand for crude oil and thus, the demand for the Company's products and services, as well as delays in or inability of the Company to fulfill its contractual obligations to customers, logistic constraints, increases in the Company's costs, workforce shortages and unavailability of raw materials. The Company continues to monitor the effect of COVID-19 on its employees, customers, critical suppliers and other stakeholders. The ultimate duration of the COVID-19 pandemic, the resulting governmental restrictions and the related impact on the prices of and the demand for crude oil and the United States and global economy and capital markets remains uncertain. 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. Following the GEODynamics Acquisition in January 2018, the Company determined that certain steel products historically imported by GEODynamics from China for use in its manufacturing process were potentially subject to anti-dumping and countervailing duties. Following an internal review, the Company voluntarily disclosed this matter to U.S. Customs and Border Protection ("CBP") and, in December 2020, reached an agreement with CBP to settle this matter for $7.3 million. The Company believes that the Seller is required to indemnify and hold the Company harmless against the amount of this and other settlements and related costs of $7.5 million, and the Company has provided notice to and asserted indemnification claims against the Seller. Additionally, the Company believes that its agreements with the Seller allow it to set-off such amounts against payments due under the $25.0 million promissory note and that, because the Company has asserted indemnification claims, the maturity date of such note is extended until the resolution of such claims. Accordingly, the Company reduced the carrying amount of such note in its consolidated balance sheet to $17.5 million as of September 30, 2021, which is the Company's current best estimate of what is owed after set-off for such indemnification matters. In August 2020, the Seller filed a breach of contract suit against the Company and one of its wholly-owned subsidiaries in federal court alleging that payments due under the promissory note are required to be, but have not been, repaid in accordance with the terms of the note. Additionally, the Seller alleged that it was entitled to approximately $19.0 million in U.S. federal income tax carryback claims received by the Company under the provisions of the CARES Act. On February 15, 2021, the Seller dismissed the federal lawsuit without prejudice and refiled its lawsuit in state court. On September 20, 2021, a motion by the Seller for partial summary judgement was dismissed. The Company denies the validity of these breach of contract claims and plans to vigorously defend against this lawsuit.

Accounting Policies [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 August 2020, the FASB issued updated guidance to simplify the accounting for convertible instruments and contracts in an entity's own equity (referred to as "ASU 2020-06"). This guidance eliminated the requirement that the carrying value of convertible debt instruments, such as the Company's 1.50% convertible senior notes due 2023 (the "2023 Notes"), be allocated between debt and equity components. As permitted under the standard, the Company adopted the guidance on January 1, 2021, using the modified retrospective transition method. Adoption of the standard resulted in a $12.2 million increase in the net carrying value of the 2023 Notes, a $2.7 million decrease in deferred income taxes and a $9.5 million net decrease in stockholders' equity. The effective interest rate associated with the 2023 Notes after adoption decreased from approximately 6% to approximately 2%, which compares to the contractual interest rate of 1.50%. As further discussed in Note 5, "Long-term Debt," the Company issued $135.0 million principal amount of its 4.75% convertible senior notes due 2026 (the "2026 Notes") on March 19, 2021, which have been accounted for in accordance with the provisions of ASU 2020-06.
