| Commitments and Contingencies Disclosure                | NOTE 10 - COMMITMENTS AND CONTINGENCIES  Contractual Obligations. We routinely enter into, extend or amend operating agreements in the ordinary course of business. We have long-term transportation, sales, processing and facility expansion agreements for pipeline capacity and water delivery and disposal commitments. There were no significant commitments entered into during the three months ended March 31, 2023. For details of our existing commitments, refer to Note 12 - Commitments and Contingencies in Item 8. Financial Statements and Supplementary Data included in our 2022 Form 10-K. Lease Commitments. In March 2023, we commenced two long-term drilling rig leases. We recognized right-of-use of assets and operating lease liabilities in an aggregate amount of $45 million. Additionally, we had short-term lease costs of $168 million and $75 million for the three months ended March 31, 2023 and March 31, 2022, respectively. Our short-term lease costs include amounts that are capitalized as part of the cost of assets and are recorded as properties and equipment, or recognized as expense.Litigation and Legal Items.We are involved in various legal proceedings. We review the status of these proceedings on an ongoing basis and, from time to time, may settle or otherwise resolve these matters on terms and conditions that management believes are in our best interests. We have provided the necessary estimated accruals in the accompanying condensed consolidated balance sheets where deemed appropriate for litigation and legal related items that are ongoing and not yet concluded. Although the results cannot be known with certainty, we currently believe that the ultimate results of such proceedings will not have a material adverse effect on our financial position, results of operations or liquidity. |
