Accounting Policies [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that were entered into on or before December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" (ASU 2022-06), which deferred the sunset date of Topic 848 until December 31, 2024. EOG has evaluated the provisions of ASU 2020-04 and ASU 2022-06 and has concluded that their application will not have a material impact on EOG's consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.
