STANLEY
STANLEY is a Texas oil lease in Cass County, Railroad Commission district 06, operated by Rose City Resources, LLC. It has 1 wellbore on file with the Commission. Reported production runs from December 2022 to August 2026, totalling 440,792 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 $5.5M, with roughly $2.7M 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 5,282 barrels a month. Its strongest month on the record we hold was January 2023, at 22,054 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.
