EL REY 28-16
EL REY 28-16 is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Endeavor Energy Resources L.P. It has 5 wellbores on file with the Commission. Reported production runs from December 2024 to August 2026, totalling 912,554 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 $16.9M, with roughly $14.1M 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 72,876 barrels a month, about 14,575 per wellbore. Its strongest month on the record we hold was June 2025, at 149,004 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
