JO-MILL UNIT
JO-MILL UNIT is a Texas oil lease in Borden County, Railroad Commission district 8A, operated by Texaco E & P Inc. It has 487 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 46,128,107 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 $160.6M, with roughly $36.3M 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 48,681 barrels a month, about 100 per wellbore. Its strongest month on the record we hold was May 2016, at 92,190 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
