GRAWUNDER, HERMAN
GRAWUNDER, HERMAN is a Texas oil lease in Austin County, Railroad Commission district 03, operated by Hamman Oil & Refining Company. It has 2 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 28,018 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 $577K, with roughly $111K 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 136 barrels a month, about 68 per wellbore. Its strongest month on the record we hold was June 2022, at 328 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.
