CASSELMAN10
CASSELMAN10 is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Henry Resources LLC. It has 26 wellbores on file with the Commission. Reported production runs from July 2008 to August 2026, totalling 2,573,264 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 $14.6M, with roughly $3.8M 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 4,772 barrels a month, about 184 per wellbore. Its strongest month on the record we hold was November 2018, at 71,911 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.
