CAUBLE 21-30 F
CAUBLE 21-30 F is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Diamondback E&P LLC. It has 1 wellbore on file with the Commission. Reported production runs from June 2025 to August 2026, totalling 101,829 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 $17.6M, with roughly $3.7M 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 8,884 barrels a month. Its strongest month on the record we hold was July 2025, at 24,643 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.
