COX
COX is a Texas oil lease in Rusk County, Railroad Commission district 6E, operated by 4-Sight Operating Company. It has 5 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 34,981 barrels. The lease is intermittent. 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 $16K, with roughly $3K 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 2 barrels a month. Its strongest month on the record we hold was May 2016, at 62 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
