CLARK 15A
CLARK 15A is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Endeavor Energy Resources L.P. It has 2 wellbores on file with the Commission. Reported production runs from December 2020 to August 2026, totalling 14,768 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 $624K, with roughly $150K 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 279 barrels a month, about 140 per wellbore. Its strongest month on the record we hold was April 2026, at 1,185 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.
