CALVIN-STARNES UNIT
CALVIN-STARNES UNIT is a Texas oil lease in Cochran County, Railroad Commission district 8A, operated by BHP Petroleum (Americas) Inc. It has 131 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 1,486,894 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 $2.0M, with roughly $516K 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 333 barrels a month, about 3 per wellbore. Its strongest month on the record we hold was September 2022, at 1,454 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.
