COX -A-
COX -A- is a Texas oil lease in Rusk County, Railroad Commission district 6E, operated by Phillips Petroleum Company. It has 4 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 118,803 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 $254K, with roughly $49K 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 67 barrels a month, about 17 per wellbore. Its strongest month on the record we hold was May 2025, at 74 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
