GRINKE

GRINKE is a Texas oil lease in Clay County, Railroad Commission district 09, operated by Continental Export Corporation. It has 3 wellbores on file with the Commission. Reported production runs from January 1994 to August 2026, totalling 72,187 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 $163K, with roughly $31K 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 55 barrels a month, about 18 per wellbore. Its strongest month on the record we hold was August 2025, at 139 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
