HORST WEST
HORST WEST is a Texas gas lease in San Augustine County, Railroad Commission district 06, operated by Aethon Energy Operating LLC. It has 1 wellbore on file with the Commission. Reported production runs from February 2025 to August 2026, totalling 7,243,768 thousand cubic feet. The lease is intermittent. 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 $101.6M, with roughly $15.4M 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 535,161 thousand cubic feet a month. Its strongest month on the record we hold was March 2026, at 829,780 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.
