Accounting Policies [Abstract]
Description of Business and Basis of Presentation	Note 1 - Description of Business and Basis of Presentation Description of Business Exterran Corporation (together with its subsidiaries, “Exterran Corporation,” the “Company,” “our,” “we” or “us”), a Delaware corporation formed in March 2015, is a global sustainable systems and process company offering solutions in the oil, gas, water and power markets. We are a leader in natural gas processing and treatment, produced water treatment and compression products, solutions and services, providing critical midstream infrastructure solutions to customers throughout the world. We provide our products, solutions, and services to a global customer base consisting of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national oil and natural gas companies, independent oil and natural gas producers and oil and natural gas processors, gatherers and pipeline operators. Our manufacturing facilities are located in the United States of America (“U.S.”), Singapore and the United Arab Emirates. We operate in three primary business lines: contract operations, aftermarket services and product sales. In our contract operations business line, we provide processing, treating, compression and water treatment services through the operation of our natural gas and crude oil production and process equipment and natural gas compression equipment and water treatment equipment for our customers. In our aftermarket services business line, we sell parts and components and provide operations, maintenance, repair, overhaul, upgrade, startup and commissioning and reconfiguration services to customers who own their own oil and natural gas compression, production, processing, treating and related equipment. In our product sales business line, we design, engineer, manufacture, install and sell equipment used in the treating and processing of crude oil, natural gas, natural gas compression packages and water to our customers throughout the world and for use in our contract operations business line. We also offer our customers, on either a contract operations basis or a sale basis, the engineering, design, project management, procurement and construction services necessary to incorporate our products into production, processing and compression facilities, which we refer to as integrated projects. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Exterran Corporation included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S.”) (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP are not required in these interim financial statements and have been condensed or omitted. Management believes that the information furnished includes all adjustments of a normal recurring nature that are necessary to fairly state our consolidated financial position, results of operations and cash flows for the periods indicated. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our Annual Report on Form 10-K for the year ended December 31, 2020. That report contains a comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year. We refer to the consolidated financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein. In March 2020, the World Health Organization declared the outbreak of the novel coronavirus (“COVID-19”) a pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption across most industries. Efforts to mitigate the spread of COVID-19 have also resulted in decreased energy demand and additional weakness in energy pricing. To help control the spread of the virus and protect the health and safety of our employees and customers, we began temporarily closing our locations or modifying operating hours in our locations around the world. This was in response to governmental requirements including “stay-at-home” orders and similar mandates and in some of our locations, we voluntarily went beyond the requirements of local government authorities. The broader implications of COVID-19 on our long-term future results of operations and overall financial condition remains uncertain. Due to the rapid market deterioration during the three months ended March 31, 2020, we concluded that a trigger existed and that we should evaluate our long-term assets for impairment. Therefore, we updated our impairment analysis and concluded that no impairment existed during the three months ended March 31, 2020. No triggering events were identified subsequent to March 31, 2020. Recent Accounting Pronouncements We consider the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not listed below were assessed and determined to be not applicable. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”): Simplifying the Accounting for Income Taxes. The update simplifies the accounting for income taxes and is effective for annual and interim periods beginning after December 15, 2020, with early adoption permitted. On January 1, 2021, we adopted this update. The adoption of this update was immaterial to our financial statements. In June 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04) . Topic 848 is effective for fiscal years and interim periods beginning as of March 12, 2020 through December 31, 2022. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for reference rate reform on financial reporting. It is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The adoption of ASU 2020-04 did not have a material impact to our financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted There are no recently issued accounting pronouncements not yet adopted that we are aware of at this time that would have a material impact on the Company.

(2) Revenue recognized at a point in time. (3) Compression equipment includes sales to customers outside of the U.S. The compression fabrication business for sales to U.S. customers that was previously included in our product sales segment is now included in discontinued operations.

The Middle East and Africa region is primarily comprised of our operations in Bahrain, Iraq, Oman, Nigeria and the United Arab Emirates. The Asia Pacific region is primarily comprised of our operations in China, Indonesia, Singapore and Thailand. The following table summarizes the expected timing of revenue recognition from unsatisfied performance obligations (commonly referred to as backlog) as of March 31, 2021 (in thousands): Contract Operations Segment Product Sales Segment Remainder of 2021 $ 215,012 $ 149,838 2022 213,560 205,167 2023 203,346 59,556 2024 186,322 13,000 2025 161,876 17,500 Thereafter 247,538 — Total backlog $ 1,227,654 $ 445,061 Certain of our aftermarket services contracts are subject to cancellation or modification at the election of the customer. If the primary component of our contract operations contracts is the lease component, the contracts are accounted for as operating leases. For these contracts, revenues are recognized on a straight-line basis. As of March 31, 2021, the total value of our contracts operations backlog accounted for as operating leases was approximately $300.5 million, of which $33 million is expected to be recognized in the remainder of 2021, $43 million is expected to be recognized in 2022, $77 million is expected to be recognized in 2023, $65 million is expected to be recognized in 2024 and $47 million is expected to be recognized in 2025. Contract operations revenue recognized as operating leases for the three months ended March 31, 2021 was approximately $9 million. Our product sales backlog includes contracts where there is a significant financing component. As of March 31, 2021, we had approximately $43 million expected to be recognized in future periods as interest income within our product sales segment. Contract Assets and Contract Liabilities The following table provides information about accounts receivables, net, contract assets and contract liabilities from contracts with customers (in thousands): March 31, 2021 December 31, 2020 Accounts receivables, net $ 188,401 $ 198,028 Contract assets and contract liabilities: Current contract assets 32,301 32,642 Long-term contract assets 19,324 33,563 Current contract liabilities 97,753 100,123 Long-term contract liabilities 65,580 80,499 During the three months ended March 31, 2021, revenue recognized from contract operations services included $15.8 million of revenue deferred in previous periods. Revenue recognized during the three months ended March 31, 2021 from product sales performance obligations partially satisfied in previous periods was $27.8 million, of which $16.4 million was included in billings in excess of costs at the beginning of the period. The decrease in long-term contract assets during the three months ended March 31, 2021 was primarily due to the timing of milestones billings in the Middle East and Africa region. The decrease in current contract liabilities during the three months ended March 31, 2021 was primarily driven by the progression of product sales projects and the timing of milestones billings in the Middle East and Africa region. The decrease in long-term contract liabilities during the three months ended March 31, 2021 was primarily driven by the change in the remaining term of a contract operation services contract in the Latin America region. Allowance for Doubtful Accounts The Company estimates its reserves using information about past events, current conditions and risk characteristics of each customer, and reasonable and supportable forecasts relevant to assessing risk associated with the collectability of accounts receivables, contract assets and long-term note receivables. The Company’s customer base has generally similar collectability risk characteristics, although larger customers may have lower risk than smaller independent customers. The allowance for doubtful accounts as of March 31, 2021 and changes for the three months then ended are as follows (in thousands): Balance at December 31, 2020 $ 10,803 Write-offs during the period (48) Balance at March 31, 2021 $ 10,755

Discontinued Operations

Discontinued Operations	3 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 3 - Discontinued Operations We have continued to work toward our strategy to be a company that leverages technology and operational excellence to provide complete systems and process solutions in energy and industrial applications. Over the past several years, we have made significant progress in this journey by taking actions to protect our core business, develop important organizational capabilities, commercialize new products, solutions, and services and implement new processes to position Exterran for success. We are focused on optimizing our portfolio of products and services to better serve our global customers while providing a more attractive investment option for our investors. As we continue on this path, we decided that our U.S. compression fabrication business was non-core to our strategy, and during the third quarter of 2020, we entered into an agreement to sell the assets used to operate the business which closed on November 2, 2020. We did not sell certain items in inventory, which we expect to liquidate over time. During the third quarter of 2020, this business met the held for sale criteria and is now reflected as discontinued operations in our financial statements for all periods presented. The U.S. compression fabrication business was previously included in our product sales segment and has been reclassified to discontinued operations in our financial statements for all periods presented. Compression revenue from sales to international customers continues to be included in our product sales segment. In the first quarter of 2016, we began executing the exit of our Belleli EPC business that has historically been comprised of engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein) by ceasing the bookings of new orders. As of the fourth quarter of 2017, we had substantially exited our Belleli EPC business and, in accordance with GAAP, it is reflected as discontinued operations in our financial statements for all periods presented. Although we have reached mechanical completion on all remaining Belleli EPC contracts, we are still subject to risks and uncertainties potentially resulting from warranty obligations, customer or supplier claims against us, settlement of claims against customers, completion of demobilization activities and litigation developments. The facility previously utilized to manufacture products for our Belleli EPC business has been repurposed to manufacture product sales equipment.

(“EESLP”), are parties to an amended and restated credit agreement (the “Amended Credit Agreement”) consisting of a $650.0 million revolving credit facility expiring in October 2023. As of March 31, 2021, we had $223.7 million in outstanding borrowings and $7.5 million in outstanding letters of credit under our revolving credit facility. At March 31, 2021, taking into account guarantees through letters of credit, we had undrawn capacity of $418.8 million under our revolving credit facility. Our Amended Credit Agreement limits our Total Debt to EBITDA ratio (as defined in the Amended Credit Agreement) on the last day of the fiscal quarter to no greater than 4.50 to 1.0. As a result of this limitation, $109.8 million of the $418.8 million of undrawn capacity under our revolving credit facility was available for additional borrowings as of March 31, 2021. 8.125% Senior Notes Due May 2025 In April 2017, our 100% owned subsidiaries EESLP and EES Finance Corp. issued $375.0 million aggregate principal amount of 8.125% senior unsecured notes due 2025 (the “2017 Notes”) which have $350.0 million outstanding as of March 31, 2021. We guarantee the 2017 Notes on a senior unsecured basis. We may redeem the 2017 Notes at any time in cash, in whole or part, at certain redemption prices, including the applicable make-whole premium plus accrued and unpaid interest, if any, to the date of redemption.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7 - Fair Value Measurements The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into the following three categories: • Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the date of measurement. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered market makers. • Level 3 — Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information. Recurring Fair Value Measurements The following table presents our assets and liabilities measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020, with pricing levels as of the date of valuation (in thousands): March 31, 2021 December 31, 2020 (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) Foreign currency derivatives liabilities $ — $ — $ — $ — $ — $ (247) We are exposed to market risks associated with changes in foreign currency exchange rates, including foreign currency exchange rate changes recorded on intercompany obligations. From time to time, we may enter into foreign currency hedges to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on our balance sheets including intercompany activity. As of March 31, 2021, we were a party to forward currency exchange contracts to mitigate exposures to the Argentine Peso with a total notional value of $25.0 million. These contracts expire at varying dates through June 2021. We did not designate these forward currency exchange contracts as hedge transactions. Changes in fair value and gains and losses on settlement on these forward currency exchange contracts are recognized in other (income) expense, net, in our statements of operations. Our estimate of the fair value of foreign currency derivatives as of March 31, 2021 was determined using quoted forward exchange rates in active markets at March 31, 2021. Foreign currency derivative assets are included in other current assets in our balance sheets. During the three months ended March 31, 2021, we recognized a loss of $0.9 million on forward currency exchange contracts. Nonrecurring Fair Value Measurements The following table presents our assets and liabilities measured at fair value on a nonrecurring basis during the three months ended March 31, 2021 and 2020, with pricing levels as of the date of valuation (in thousands): Three months ended March 31, 2021 Three months ended March 31, 2020 (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) Long-term note receivable (1) $ — $ — $ 11,767 $ — $ — $ 15,039 (1) Our estimate of the fair value of a note receivable was discounted based on a settlement period of eight years and a discount rate of 12.5%. The undiscounted value of the note receivable, including interest, as of March 31, 2021 was $15.7 million. Financial Instruments Our financial instruments consist of cash, restricted cash, receivables, payables and debt. At March 31, 2021 and December 31, 2020, the estimated fair values of cash, restricted cash, receivables and payables approximated their carrying amounts as reflected in our balance sheets due to the short-term nature of these financial instruments. The fair value of the 2017 Notes was estimated based on model derived calculations using market yields observed in active markets, which are Level 2 inputs. As of March 31, 2021 and December 31, 2020, the carrying amount of the 2017 Notes, excluding unamortized deferred financing costs, of $350.0 million was estimated to have a fair value of $324.0 million and $297.0 million, respectively. Due to the variable rate nature of our revolving credit facility, the carrying value as of March 31, 2021 and December 31, 2020 approximated the fair value as the rate was comparable to the then-current market rate at which debt with similar terms could have been obtained.

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges	Note 8 - Restructuring and Other Charges The energy industry’s focus on cash flow, capital discipline and improving returns has caused delays in the timing of new equipment orders. As a result, in the third quarter of 2019, we announced a cost reduction plan primarily focused on workforce reductions. We incurred restructuring and other charges associated with these activities of $0.6 million and $0.2 million for the three months ended March 31, 2021 and 2020, respectively. These charges are reflected as restructuring and other charges in our statements of operations and accrued liabilities on our balance sheets. The cost reduction plan is expected to be completed in the first half of 2021 and we expect to settle these charges within the next twelve months in cash. At this time, we cannot currently estimate the total restructuring costs that will be incurred as a result of this cost reduction plan. The following table summarizes the changes to our accrued liability balance related to restructuring and other charges for the three months ended March 31, 2021 and 2020 (in thousands): Cost Beginning balance at January 1, 2020 $ 2,281 Additions for costs expensed, net 207 Reductions for payments (163) Foreign exchange impact (289) Ending balance at March 31, 2020 $ 2,036 Beginning balance at January 1, 2021 $ 1,351 Additions for costs expensed, net 624 Reductions for payments (588) Foreign exchange impact (94) Ending balance at March 31, 2021 $ 1,293 The following table summarizes the components of charges included in restructuring and other charges in our statements of operations for the three months ended March 31, 2021 and 2020 (in thousands): Three Months Ended March 31, 2021 2020 Employee termination benefits $ 624 $ — Consulting fees — 207 Total restructuring and other charges $ 624 $ 207 The following table summarizes the components of charges included in restructuring and other charges incurred since the announcement of the cost reduction plan in the second quarter of 2019 (in thousands): Total Employee termination benefits $ 6,867 Consulting fees 3,205 Total restructuring and other charges $ 10,072

Income Tax Disclosure [Abstract]
Provision for Income Taxes	Note 9 - Provision for Income Taxes Our effective tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn, or losses we incur, in those jurisdictions. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. Our effective tax rate is also affected by valuation allowances recorded against loss carryforwards in the U.S. and certain other jurisdictions, foreign withholding taxes and changes in foreign currency exchange rates. The following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 21% and our effective tax rate of (34.6)% for the three months ended March 31, 2021: (i) a 6.7% positive impact resulting from unrecognized tax benefits under FASB’s Interpretation No. 48 of Financial Accounting Standard 109 (“FIN 48”), (ii) a (12.1)% negative impact resulting from foreign currency devaluations in Argentina, (iii) a (20.2)% negative impact resulting from foreign taxes in excess of the U.S. tax rate and other rate drivers, (iv) a (12.6)% negative impact resulting from deemed inclusions in the U.S. and (v) a (9.5)% negative impact resulting from an addition of valuation allowances against U.S. deferred tax assets. Our effective tax rate increased for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 primarily due to a decrease in valuation allowances recorded in the U.S., an increase in foreign taxes in excess of the U.S. tax rate, an increase in deemed inclusions in the U.S., a decrease in the FIN 48 reserve and an increase in tax related to foreign exchange movement in Argentina.

Equity [Abstract]
Stockholders' Equity	Note 10 - Stockholders’ Equity Share Repurchase Program On February 20, 2019, our board of directors approved a share repurchase program under which the Company is authorized to purchase up to $100.0 million of its outstanding common stock through February 2022. The timing and method of any repurchases under the program will depend on a variety of factors, including prevailing market conditions among others. Purchases under the program may be suspended or discontinued at any time and we have no obligation to repurchase any amount of our common shares under the program. Shares of common stock acquired through the repurchase program are held in treasury at cost. During the three months ended March 31, 2021 and 2020, we did not repurchase any shares under this program. As of March 31, 2021, the remaining authorized repurchase amount under the share repurchase program was $57.7 million. Additionally, treasury stock purchased during the three months ended March 31, 2021 and 2020 included shares withheld to satisfy employees’ tax withholding obligations in connection with vesting of restricted stock awards.

Earnings Per Share [Abstract]
Net Income (Loss) Per Common Share	Note 12 - Net Income (Loss) Per Common Share Basic net income (loss) per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) per common share is determined by dividing net income (loss) after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include unvested restricted stock and restricted stock units that have non-forfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss from continuing operations, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses. Diluted net income (loss) per common share is computed using the weighted average number of common shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options to purchase common stock and non-participating restricted stock units, unless their effect would be anti-dilutive. The following table presents a reconciliation of basic and diluted net loss per common share for the three months ended March 31, 2021 and 2020 (in thousands, except per share data): Three Months Ended March 31, 2021 2020 Numerator for basic and diluted net loss per common share: Loss from continuing operations $ (29,000) $ (16,073) Loss from discontinued operations, net of tax (873) (2,231) Less: Net income attributable to participating securities — — Net loss — used in basic and diluted net loss per common share $ (29,873) $ (18,304) Weighted average common shares outstanding including participating securities 33,229 33,163 Less: Weighted average participating securities outstanding (279) (510) Weighted average common shares outstanding — used in basic net loss per common share 32,950 32,653 Net dilutive potential common shares issuable: On exercise of options and vesting of restricted stock units * * Weighted average common shares outstanding — used in diluted net loss per common share 32,950 32,653 Net loss per common share: Basic and diluted $ (0.91) $ (0.56) * Excluded from diluted net income (loss) per common share as their inclusion would have been anti-dilutive.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13 - Commitments and Contingencies Contingencies We have agreements with financial institutions under which approximately $62.6 million of letters of credit or bank guarantees were outstanding as of March 31, 2021. These are put in place in certain situations to guarantee our performance obligations under contracts with counterparties. In addition to U.S. federal, state and local and foreign income taxes, we are subject to a number of taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of March 31, 2021 and December 31, 2020, we had accrued $1.5 million and $3.5 million, respectively, for the outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We do not have any unasserted claims from non-income based tax audits that we have determined are probable of assertion. We also believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our financial position, but it is possible that the resolution of future audits could be material to our results of operations or cash flows for the period in which the resolution occurs. Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability, commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs. Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. Litigation and Claims On December 19, 2020, we initiated arbitration in the International Court of Arbitration of the International Chamber of Commerce (“ICC”) against Iberoamericana de Hidrocarburos, S.A. De C.V. (“IHSA”) to collect approximately $38 million owed to us under three agreements, plus future lost profits, interest, attorneys’ fees, and other damages as allowed under the contracts and/or Mexican law. The three agreements relate to contract operation services provided to IHSA by Exterran. After we stopped providing services due to IHSA’s nonpayment, on December 29, 2020, IHSA filed a lawsuit in the 129th Judicial District Court of Harris County, Texas, for tortious interference with a contract and prospective business relationships, claiming damages for lost profits, lost production, loss of equipment, loss of business opportunity, damage to business reputation and attorneys’ fees. On March 2, 2021, after we moved IHSA’s lawsuit to the United States District Court for the Southern District of Texas, IHSA voluntarily dismissed the lawsuit. On April 27, 2021, IHSA answered Exterran’s request for arbitration before the ICC and included a counterclaim for approximately $27 million allegedly resulting from breach of contract, operational deficiencies, lost production, and lost profit. In addition, IHSA has orally threatened to draw certain bonds totaling approximately $12 million under one of the contracts for contract operation services. Based on currently available information we believe IHSA’s claims are without merit; however, IHSA’s claim are in the early stages and the results cannot be predicted with certainty. In the ordinary course of business, we are involved in various pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our financial position, results of operations or cash flows. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our financial position, results of operations or cash flows.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Exterran Corporation included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S.”) (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP are not required in these interim financial statements and have been condensed or omitted. Management believes that the information furnished includes all adjustments of a normal recurring nature that are necessary to fairly state our consolidated financial position, results of operations and cash flows for the periods indicated. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our Annual Report on Form 10-K for the year ended December 31, 2020. That report contains a comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year. We refer to the consolidated financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein. In March 2020, the World Health Organization declared the outbreak of the novel coronavirus (“COVID-19”) a pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption across most industries. Efforts to mitigate the spread of COVID-19 have also resulted in decreased energy demand and additional weakness in energy pricing. To help control the spread of the virus and protect the health and safety of our employees and customers, we began temporarily closing our locations or modifying operating hours in our locations around the world. This was in response to governmental requirements including “stay-at-home” orders and similar mandates and in some of our locations, we voluntarily went beyond the requirements of local government authorities. The broader implications of COVID-19 on our long-term future results of operations and overall financial condition remains uncertain. Due to the rapid market deterioration during the three months ended March 31, 2020, we concluded that a trigger existed and that we should evaluate our long-term assets for impairment. Therefore, we updated our impairment analysis and concluded that no impairment existed during the three months ended March 31, 2020. No triggering events were identified subsequent to March 31, 2020.
Recent Accounting Pronouncements	Recent Accounting Pronouncements We consider the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not listed below were assessed and determined to be not applicable. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”): Simplifying the Accounting for Income Taxes. The update simplifies the accounting for income taxes and is effective for annual and interim periods beginning after December 15, 2020, with early adoption permitted. On January 1, 2021, we adopted this update. The adoption of this update was immaterial to our financial statements. In June 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04) . Topic 848 is effective for fiscal years and interim periods beginning as of March 12, 2020 through December 31, 2022. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for reference rate reform on financial reporting. It is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The adoption of ASU 2020-04 did not have a material impact to our financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted There are no recently issued accounting pronouncements not yet adopted that we are aware of at this time that would have a material impact on the Company.
