MASON, T. O.
MASON, T. O. is a Texas oil lease in Rusk County, Railroad Commission district 6E, operated by Mobil Producing TX. & N.M. Inc. It has 30 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 364,811 barrels. 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 $1.3M, with roughly $297K 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 456 barrels a month, about 15 per wellbore. Its strongest month on the record we hold was December 2019, at 738 barrels. 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.
