KOONCE FARMS "15"

KOONCE FARMS "15" is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Endeavor Energy Resources L.P. It has 2 wellbores on file with the Commission. Reported production runs from January 2011 to August 2026, totalling 145,888 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 $902K, with roughly $167K 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 286 barrels a month, about 143 per wellbore. Its strongest month on the record we hold was July 2017, at 2,116 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.
