Accounting Policies [Abstract]
Fair Value of Financial Instruments	The fair values of cash and cash equivalents, receivables and payables were approximately the same as their presented carrying values because of the short maturities of these instruments. The fair value of long-term debt is provided in Note 8, and the fair values of derivative financial instruments are provided in Note 11.
Net Income (Loss) Attributable to Company Per Share	Companies with unvested participating securities are required to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method allocates a portion of net income attributable to Company to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents if declared. Net income (loss) attributable to Company allocated to participating securities was immaterial for each of the three and nine months ended September 30, 2020 and 2019, respectively.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments. This update improves financial reporting by requiring earlier recognition of forecast credit losses on financing receivables and other financial assets in scope. ASU 2016-13 is effective for fiscal periods beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this update on January 1, 2020, with no material impact. 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 Trade Accounts Receivables, Contract Assets, Unbilled Accounts Receivables, and Long-Term Receivables. The Company’s customer base, mostly in the oil and gas industry, have generally similar collectability risk characteristics, although larger and state-owned customers may have lower risk than smaller independent customers. As of September 30, 2020, allowance for bad debts and contract assets totaled $115 million. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” This ASU eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of accounting for income taxes. ASU 2019-12 is effective for interim and annual reporting periods beginning after December 15, 2020, with early adoption permitted. Management is currently assessing the impact of adopting ASU 2019-12 on the Company’s financial position, results of operations and cash flows.

The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship.
