STUMBERG-KING UNIT
STUMBERG-KING UNIT is a Texas oil lease in Dimmit County, Railroad Commission district 01, operated by Murphy Expl. & Prod. Co. - USA. It has 4 wellbores on file with the Commission. Reported production runs from June 2015 to August 2026, totalling 704,829 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 $2.3M, with roughly $745K 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 1,320 barrels a month, about 330 per wellbore. Its strongest month on the record we hold was May 2016, at 27,578 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
