MAHANEY 35
MAHANEY 35 is a Texas oil lease in Dawson County, Railroad Commission district 08, operated by Big Star Oil & Gas, LLC. It has 1 wellbore on file with the Commission. Reported production runs from March 2014 to August 2026, totalling 18,936 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 $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 37 barrels a month. Its strongest month on the record we hold was October 2024, at 561 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.
