GEASLIN 186
GEASLIN 186 is a Texas gas lease in Terrell County, Railroad Commission district 7C, operated by Fasken Oil And Ranch, Ltd. It has 1 wellbore on file with the Commission. Reported production runs from June 1999 to August 2026, totalling 1,277,302 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 $4K, with roughly $502 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 30 thousand cubic feet a month. Its strongest month on the record we hold was April 2023, at 4,529 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
