WELLMAN WEST UNIT
WELLMAN WEST UNIT is a Texas oil lease in Terry County, Railroad Commission district 8A, operated by Santa Fe Energy Oper. Part., LP. It has 45 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 2,043,102 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 $3.4M, with roughly $869K 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 1,267 barrels a month, about 28 per wellbore. Its strongest month on the record we hold was March 2017, at 3,003 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
