OVERTON GU 21
OVERTON GU 21 is a Texas gas lease in Smith County, Railroad Commission district 06, operated by Exxon Corp. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 1,470,806 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 $461, with roughly $58 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 2 thousand cubic feet a month. Its strongest month on the record we hold was October 2016, at 2,945 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
