CASTLE
CASTLE is a Texas gas lease in Reeves County, Railroad Commission district 08, operated by Coterra Energy Operating Co. It has 1 wellbore on file with the Commission. Reported production runs from November 2025 to August 2026, totalling 1,425,844 thousand cubic feet. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values the whole lease — a 100% undivided interest — at about $8.5M, with roughly $7.5M expected over the next twelve months. An individual royalty owner receives their own decimal interest times that figure. Over the last twelve months on file it averaged 216,306 thousand cubic feet a month. Its strongest month on the record we hold was December 2025, at 345,038 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 18% of what they went on to produce, and that measured error is the range shown on the page rather than a confidence of our own devising.
