BLACK CAIMAN 21-24 E
BLACK CAIMAN 21-24 E is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 2 wellbores on file with the Commission. Reported production runs from January 2026 to August 2026, totalling 63,536 barrels. The lease is intermittent. 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 $12.4M, with roughly $2.4M 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 3,062 barrels a month, about 1,531 per wellbore. Its strongest month on the record we hold was April 2026, at 12,247 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
