GEASLIN SW 198
GEASLIN SW 198 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 January 2002 to August 2026, totalling 668,879 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 $4K, with roughly $445 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 106 thousand cubic feet a month. Its strongest month on the record we hold was April 2023, at 2,201 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
