ALLISON 18
ALLISON 18 is a Texas gas lease in Terrell County, Railroad Commission district 7C, operated by Eog Resources, Inc. It has 1 wellbore on file with the Commission. Reported production runs from July 2003 to August 2026, totalling 793,223 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 $5K, with roughly $4K 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 1,027 thousand cubic feet a month. Its strongest month on the record we hold was March 2025, at 4,281 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
