T-REX
T-REX is a Texas oil lease in Fayette County, Railroad Commission district 03, operated by Enervest Operating, L.L.C. It has 1 wellbore on file with the Commission. Reported production runs from September 2011 to August 2026, totalling 64,109 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 $467K, with roughly $88K 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 43 barrels a month. Its strongest month on the record we hold was March 2026, at 229 barrels. 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.
