BIG MAX 12
BIG MAX 12 is a Texas oil lease in Andrews County, Railroad Commission district 08, operated by Clearfork Production, LLC. It has 2 wellbores on file with the Commission. Reported production runs from January 2012 to August 2026, totalling 112,629 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 $846K, with roughly $153K 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 227 barrels a month, about 114 per wellbore. Its strongest month on the record we hold was July 2016, at 781 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.
