RIGGS "21"
RIGGS "21" is a Texas gas lease in Crockett County, Railroad Commission district 7C, operated by Sonat Exploration Co. - Midland. It has 1 wellbore on file with the Commission. Reported production runs from May 1997 to August 2026, totalling 899,614 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 $28K, 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 1,320 thousand cubic feet a month. Its strongest month on the record we hold was June 2025, at 4,540 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.
