MUSTANG
MUSTANG is a Texas oil lease in Andrews County, Railroad Commission district 08, operated by High Sky Partners LLC. It has 14 wellbores on file with the Commission. Reported production runs from November 2009 to August 2026, totalling 774,537 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 $1.7M, with roughly $929K 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 1,547 barrels a month, about 110 per wellbore. Its strongest month on the record we hold was June 2023, at 6,569 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.
