GRANBURY, C. B. ETAL

GRANBURY, C. B. ETAL is a Texas oil lease in Polk County, Railroad Commission district 03, operated by Gei Management Co., Inc. It has 3 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 39,464 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 $486K, with roughly $93K 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 110 barrels a month, about 37 per wellbore. Its strongest month on the record we hold was January 2026, at 460 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.
