MILLS RANCH 8A
MILLS RANCH 8A is a Texas oil lease in Roberts County, Railroad Commission district 10, operated by Corlena Oil Company. It has 4 wellbores on file with the Commission. Reported production runs from January 2014 to August 2026, totalling 161,872 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 $1.7M, with roughly $318K 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 265 barrels a month, about 66 per wellbore. Its strongest month on the record we hold was May 2016, at 1,927 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.
