STUMBERG ESTATE
STUMBERG ESTATE is a Texas oil lease in Dimmit County, Railroad Commission district 01, operated by Murphy Expl. & Prod. Co. - USA. It has 37 wellbores on file with the Commission. Reported production runs from June 2012 to August 2026, totalling 6,677,583 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 $30.2M, with roughly $12.6M 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 25,058 barrels a month, about 677 per wellbore. Its strongest month on the record we hold was October 2019, at 201,773 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.
