DUFFY -A-
DUFFY -A- is a Texas oil lease in Wharton County, Railroad Commission district 03, operated by Stinger Oil & Gas Inc. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 108,073 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 $724K, with roughly $139K 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 235 barrels a month. Its strongest month on the record we hold was October 2025, at 680 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.
