FILLINGIM 40

FILLINGIM 40 is a Texas gas lease in Hemphill County, Railroad Commission district 10, operated by Samson Lone Star LP. It has 1 wellbore on file with the Commission. Reported production runs from August 2005 to August 2026, totalling 479,779 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 $55K, with roughly $7K 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 222 thousand cubic feet a month. Its strongest month on the record we hold was November 2021, at 3,764 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.
