COOKE

COOKE is a Texas oil lease in Cooke County, Railroad Commission district 09, operated by Biffle, Jimmy Jack. It has 23 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 156,187 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 $2.3M, with roughly $616K 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 936 barrels a month, about 41 per wellbore. Its strongest month on the record we hold was April 2021, at 2,897 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.
