CECILIA A
CECILIA A is a Texas oil lease in Sherman County, Railroad Commission district 10, operated by Phillips Petroleum Company. It has 1 wellbore on file with the Commission. Reported production runs from January 1997 to August 2026, totalling 32,400 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 $808K, with roughly $133K 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 115 barrels a month. Its strongest month on the record we hold was August 2023, at 346 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.
