MCMILLIN (CANYON SAND) UNIT
MCMILLIN (CANYON SAND) UNIT is a Texas oil lease in Stonewall County, Railroad Commission district 7B, operated by Petrotex, Inc. It has 75 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 639,841 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 $8.4M, with roughly $1.9M 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 3,131 barrels a month, about 42 per wellbore. Its strongest month on the record we hold was August 2019, at 8,995 barrels. 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.
