MAHONEY UNIT
MAHONEY UNIT is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 3 wellbores on file with the Commission. Reported production runs from January 2013 to August 2026, totalling 183,623 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 $309K, with roughly $59K 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 94 barrels a month, about 31 per wellbore. Its strongest month on the record we hold was May 2019, at 5,138 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.
