COX 27
COX 27 is a Texas gas lease in Upton County, Railroad Commission district 7C, operated by Pure Resources, L.P. It has 1 wellbore on file with the Commission. Reported production runs from January 2002 to August 2026, totalling 1,955,091 thousand cubic feet. 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 $27K, 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 67 thousand cubic feet a month. Its strongest month on the record we hold was May 2016, at 517 thousand cubic feet. 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.
