TUMLINSON-COFFIELD UNIT #1
TUMLINSON-COFFIELD UNIT #1 is a Texas oil lease in Dimmit County, Railroad Commission district 01, operated by Catarina Petroleum L. C. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 15,882 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 $13K, with roughly $2K 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 4 barrels a month. Its strongest month on the record we hold was October 2021, at 98 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.
