THOMPSON, I. W. 401
THOMPSON, I. W. 401 is a Texas oil lease in Van Zandt County, Railroad Commission district 05, operated by Union Oil Company Of California. It has 16 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 502,395 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 $690K, with roughly $130K 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 177 barrels a month, about 11 per wellbore. Its strongest month on the record we hold was March 2023, at 900 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
