STULGIS A
STULGIS 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 June 2013 to August 2026, totalling 3,060,610 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 $124.0M, with roughly $27.2M 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 67,777 barrels a month, about 5,214 per wellbore. Its strongest month on the record we hold was August 2025, at 176,993 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.
