(3) Requirements for oil and gas reserve estimation and disclosure require that reserve estimates and future cash flows be based on the average market prices for sales of oil and gas on the first calendar day of each month during the year. The benchmark price for WTI crude oil sold at Cushing, OK during 2024 and 2023 was $75.48 and $78.22 per bbl, respectively. The benchmark price for natural gas delivered at Henry Hub during 2024 and 2023 was $2.13 and $2.64 per MMBTU, respectively. Actual future prices and costs are likely to be substantially different from historical prices and costs utilized in the computation of reported amounts. Any analysis or evaluation of the reported amounts should give specific recognition to the computational methods utilized and the limitations inherent therein.
(4) Revisions of previous estimates include technical revisions due to changes in commodity prices, historical and projected performance and other factors.
