Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Risk Management Activities | Risk Management Activities Commodity Price Transactions. EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. During 2021, 2020 and 2019, EOG elected not to designate any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounted for these financial commodity derivative contracts using the mark-to-market accounting method. Under this accounting method, changes in the fair value of outstanding financial instruments are recognized as gains or losses in the period of change and are recorded as Gains (Losses) on Mark-to-Market Commodity Derivative Contracts on the Consolidated Statements of Income (Loss) and Comprehensive Income (Loss). The related cash flow impact is reflected in Cash Flows from Operating Activities. During 2021, 2020 and 2019, EOG recognized net gains (losses) on the mark-to-market of financial commodity derivative contracts of $(1,152) million, $1,145 million and $180 million, respectively, which included cash received from (payments for) settlements of crude oil, NGLs and natural gas derivative contracts of $(638) million, $1,071 million and $231 million, respectively. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts settled during the year ended December 31, 2021 (closed) and remaining for 2022 and thereafter, as of December 31, 2021. Crude oil and NGL volumes are presented in MBbld and prices are presented in $/Bbl. Natural gas volumes are presented in MMBtu per day (MMBtud) and prices are presented in dollars per MMBtu ($/MMBtu).

(2) The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $421 million, partially offset by gross assets of $29 million and collateral posted with counterparties of $123 million, at December 31, 2021.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 13). EOG evaluates its exposure to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk. At December 31, 2021, EOG's net accounts receivable balance related to United States hydrocarbon sales included three receivable balances, each of which accounted for more than 10% of the total balance. The receivables were due from three petroleum refinery companies. The related amounts were collected during early 2022. At December 31, 2020, EOG's net accounts receivable balance related to United States hydrocarbon sales included two receivable balances, each of which accounted for more than 10% of the total balance. The receivables were due from two petroleum refinery companies. The related amounts were collected during early 2021. In 2021 and 2020, all natural gas from EOG's Trinidad operations was sold to the National Gas Company of Trinidad and Tobago Limited and its subsidiary. In 2021 and 2020, all crude oil and condensate from EOG's Trinidad operations was sold to Heritage Petroleum Company Limited. Through May 2021, and in 2020, all natural gas from EOG's China operations was sold to Petrochina Company Limited. All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDA to be settled immediately. See Note 13 for the aggregate fair value of all derivative instruments that were in a net liability position at December 31, 2021 and a net asset position at December 31, 2020. EOG had $140 million of collateral posted and no collateral held at December 31, 2021, and had no collateral posted or held at December 31, 2020. Due to higher commodity prices subsequent to December 31, 2021, EOG had $1.4 billion of collateral posted at February 18, 2022. Substantially all of EOG's accounts receivable at December 31, 2021 and 2020 resulted from hydrocarbon sales and/or joint interest billings to third-party companies, including foreign state-owned entities in the oil and gas industry. This concentration of customers and joint interest owners may impact EOG's overall credit risk, either positively or negatively, in that these entities may be similarly affected by changes in economic or other conditions. In determining whether or not to require collateral or other credit enhancements from a customer, EOG typically analyzes the entity's net worth, cash flows, earnings and credit ratings. Receivables are generally not collateralized. During the three-year period ended December 31, 2021, credit losses incurred on receivables by EOG have been immaterial.
