WELCH "12"
WELCH "12" is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Endeavor Energy Resources L.P. It has 4 wellbores on file with the Commission. Reported production runs from January 2004 to August 2026, totalling 128,017 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 $284K, with roughly $53K 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 63 barrels a month, about 16 per wellbore. Its strongest month on the record we hold was January 2017, at 833 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.
