MINOTAUR 38-66 UNIT 1

MINOTAUR 38-66 UNIT 1 is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Endeavor Energy Resources L.P. It has 8 wellbores on file with the Commission. Reported production runs from January 2022 to August 2026, totalling 2,713,774 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 $37.3M, with roughly $10.7M 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 14,975 barrels a month, about 1,872 per wellbore. Its strongest month on the record we hold was March 2022, at 263,268 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.
