CORTEZ 'F'
CORTEZ 'F' is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Comstock Oil & Gas, LP. It has 2 wellbores on file with the Commission. Reported production runs from April 2013 to August 2026, totalling 448,340 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 $735K, with roughly $291K 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 496 barrels a month, about 248 per wellbore. Its strongest month on the record we hold was July 2020, at 2,274 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.
