CERF-A
CERF-A is a Texas oil lease in Navarro County, Railroad Commission district 05, operated by Activa Resources, Ltd. It has 19 wellbores on file with the Commission. Reported production runs from September 2007 to August 2026, totalling 63,143 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 $172K, with roughly $33K 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 50 barrels a month, about 3 per wellbore. Its strongest month on the record we hold was August 2016, at 523 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.
