SEWELL
SEWELL is a Texas oil lease in Jack County, Railroad Commission district 09, operated by G & F Oil, Inc. It has 2 wellbores on file with the Commission. Reported production runs from January 2016 to August 2026, totalling 4,264 barrels. 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 $53K, 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 2 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was July 2016, at 182 barrels. 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.
