CASSLE
CASSLE is a Texas oil lease in Fisher County, Railroad Commission district 7B, operated by Boyd & Mcwilliams Energy Group. It has 2 wellbores on file with the Commission. Reported production runs from July 1997 to August 2026, totalling 127,835 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 $468K, with roughly $90K 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 114 barrels a month, about 57 per wellbore. Its strongest month on the record we hold was January 2020, at 285 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
