KEYSTONE -4-
KEYSTONE -4- is a Texas oil lease in Winkler County, Railroad Commission district 08, operated by Whiting Oil And Gas Corporation. It has 1 wellbore on file with the Commission. Reported production runs from March 2019 to August 2026, totalling 6,299 barrels. The lease is intermittent. 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 $313K, with roughly $60K 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 79 barrels a month. Its strongest month on the record we hold was June 2023, at 396 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
