KOESTER
KOESTER is a Texas oil lease in Young County, Railroad Commission district 09, operated by Ada Exploration. It has 9 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 20,693 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 $65K, with roughly $13K 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 11 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was December 2019, at 70 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.
