FASKEN ZB 4143
FASKEN ZB 4143 is a Texas oil lease in Andrews County, Railroad Commission district 08, operated by Fasken Oil And Ranch, Ltd. It has 1 wellbore on file with the Commission. Reported production runs from January 2024 to August 2026, totalling 228,215 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 $6.4M, with roughly $2.5M 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 4,865 barrels a month. Its strongest month on the record we hold was February 2024, at 14,927 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.
