CASTEEL NO. 8
CASTEEL NO. 8 is a Texas oil lease in Jack County, Railroad Commission district 09, operated by Carter Energy Corporation. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 16,574 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 $163K, with roughly $31K 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 39 barrels a month. Its strongest month on the record we hold was October 2017, at 112 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
