HUMMEL-CARPENTER UNIT
HUMMEL-CARPENTER UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 2 wellbores on file with the Commission. Reported production runs from January 2013 to August 2026, totalling 271,760 barrels. The lease is intermittent. 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 $2K, with roughly $382 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 83 barrels a month, about 42 per wellbore. Its strongest month on the record we hold was September 2022, at 2,379 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.
