KING 18-35 UNIT 1B
KING 18-35 UNIT 1B is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Endeavor Energy Resources L.P. It has 6 wellbores on file with the Commission. Reported production runs from October 2023 to August 2026, totalling 864,936 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 $20.2M, with roughly $6.8M 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 22,680 barrels a month, about 3,780 per wellbore. Its strongest month on the record we hold was April 2026, at 134,864 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.
