SONNY SEIFERT A
SONNY SEIFERT A is a Texas oil lease in De Witt County, Railroad Commission district 02, operated by Geosouthern Energy Corporation. It has 13 wellbores on file with the Commission. Reported production runs from September 2012 to August 2026, totalling 3,921,945 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 $45.6M, with roughly $23.5M 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 65,074 barrels a month, about 5,006 per wellbore. Its strongest month on the record we hold was September 2025, at 166,608 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
