STASNY-PORTERFIELD EF
STASNY-PORTERFIELD EF is a Texas oil lease in Brazos County, Railroad Commission district 05, operated by Apache Corporation. It has 2 wellbores on file with the Commission. Reported production runs from February 2014 to August 2026, totalling 236,578 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 $1.3M, with roughly $288K 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 370 barrels a month, about 185 per wellbore. Its strongest month on the record we hold was May 2016, at 2,135 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.
