GRUNDEN GC
GRUNDEN GC is a Texas oil lease in Fisher County, Railroad Commission district 7B, operated by Gunn Oil Company. It has 2 wellbores on file with the Commission. Reported production runs from January 2014 to August 2026, totalling 83,742 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 $871K, with roughly $160K 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 188 barrels a month, about 94 per wellbore. Its strongest month on the record we hold was November 2018, at 1,895 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.
