Debt Disclosure [Abstract] |
Long-Term Debt | Note 5 – Long-Term Debt Credit Agreement On August 2, 2022, the Company entered into a Seventh Amended and Restated Credit Agreement by and among the Company, Wells Fargo Bank, National Association, as Administrative Agent and Swingline Lender, and the institutions named therein as lenders. The Credit Agreement provides for a senior secured revolving credit facility with a maximum loan amount of $3.0 billion. As of December 31, 2022, the borrowing base and aggregate lender commitments were $2.5 billion and $1.25 billion, respectively. The revolving credit facility is secured by substantially all of the Company’s proved oil and gas properties. The borrowing base is subject to regular, semi-annual redetermination, and considers the value of both the Company’s proved oil and gas properties reflected in the Company’s most recent reserve report; and commodity derivative contracts, each as determined by the Company’s lender group. The next scheduled borrowing base redetermination date is April 1, 2023. The Credit Agreement is scheduled to mature on the earlier of August 2, 2027 (“Stated Maturity Date”), or 91 days prior to the maturity date of any of the Company’s outstanding Senior Notes, as defined below, to the extent that, on or before such date, the respective Senior Notes have not been repaid, exchanged, repurchased, refinanced, or otherwise redeemed in full, and, if refinanced or exchanged, with a scheduled maturity date that is not earlier than at least 180 days after the Stated Maturity Date. In addition to other terms, conditions, agreements, and provisions, the Credit Agreement establishes SOFR as the benchmark for determining interest rates. The financial covenants under the Credit Agreement are discussed under Covenants below. Interest and commitment fees associated with the revolving credit facility are accrued based on a borrowing base utilization grid set forth in the Credit Agreement, as presented in the table below. At the Company’s election, borrowings under the Credit Agreement may be in the form of SOFR, Alternate Base Rate (“ABR”), or Swingline loans. SOFR loans accrue interest at SOFR plus the applicable margin from the utilization grid, and ABR and Swingline loans accrue interest at a market-based floating rate, plus the applicable margin from the utilization grid. Commitment fees are accrued on the unused portion of the aggregate lender commitment amount at rates from the utilization grid.
Borrowing Base Utilization Percentage | <25% |  | ≥25% <50% |  | ≥50% <75% |  | ≥75% <90% |  | ≥90%
SOFR Loans | 2.000 | % |  | 2.250 | % |  | 2.500 | % |  | 2.750 | % |  | 3.000 | %
ABR Loans or Swingline Loans | 1.000 | % |  | 1.250 | % |  | 1.500 | % |  | 1.750 | % |  | 2.000 | %
