MABEE 139 X4
MABEE 139 X4 is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Cog Operating LLC. It has 2 wellbores on file with the Commission. Reported production runs from January 2020 to August 2026, totalling 10,592 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 $106K 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 124 barrels a month, about 62 per wellbore. Its strongest month on the record we hold was January 2022, at 438 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.
