Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited consolidated financial statements of NOV Inc. (“NOV” or the “Company”) present information in accordance with generally accepted accounting principles (“GAAP”) in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X. They do not include all information or footnotes required by GAAP in the United States for complete consolidated financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s 2021 Annual Report on Form 10-K. Certain reclassifications have been made to prior period financial information in order to conform with current period presentation. In our opinion, the consolidated financial statements include all adjustments, which are of a normal recurring nature unless otherwise disclosed, necessary for a fair presentation of the results for the interim periods. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the full year. The preparation of financial statements in conformity with GAAP in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 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.
