MADJACK 522
MADJACK 522 is a Texas oil lease in Yoakum County, Railroad Commission district 8A, operated by Manzano, LLC. It has 6 wellbores on file with the Commission. Reported production runs from November 2014 to August 2026, totalling 1,989,742 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 $18.1M, with roughly $6.9M 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 10,537 barrels a month, about 1,756 per wellbore. Its strongest month on the record we hold was January 2021, at 48,808 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
