STATE ARMSTRONG 9-4 B

STATE ARMSTRONG 9-4 B is a Texas oil lease in Reeves County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 1 wellbore on file with the Commission. Reported production runs from March 2020 to August 2026, totalling 247,289 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 $177K, with roughly $86K 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 562 barrels a month. Its strongest month on the record we hold was July 2020, at 20,711 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.
