Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt EOG currently has a $3.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of December 3, 2030, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $3.0 billion outstanding at any given time, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $4.0 billion, subject to certain terms and conditions, and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either the Secured Overnight Financing Rate (SOFR) plus an applicable margin, or the Base Rate (as defined in the Agreement) plus an applicable margin. The applicable margin used in connection with interest rates and fees will be based on EOG’s credit rating for its senior unsecured long-term debt at the applicable time. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of Total Debt-to-Total Capitalization (as such terms are defined in the Agreement) of no greater than 65%. At March 31, 2026, EOG was in compliance with this financial covenant. At March 31, 2026 and December 31, 2025, there were no borrowings or letters of credit outstanding under the Agreement. The SOFR and Base Rate (inclusive of the applicable margins), had there been any amounts borrowed under the Agreement at March 31, 2026, would have been 4.56% and 6.75%, respectively.
