MATADOR 646 B

MATADOR 646 B is a Texas oil lease in Yoakum County, Railroad Commission district 8A, operated by Wishbone Texas Operating Co LLC. It has 4 wellbores on file with the Commission. Reported production runs from January 2018 to August 2026, totalling 689,693 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 $13.2M, with roughly $3.4M 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 5,655 barrels a month, about 1,414 per wellbore. Its strongest month on the record we hold was March 2024, at 16,430 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
