MCKEMIE
MCKEMIE is a Texas oil lease in Cooke County, Railroad Commission district 09, operated by Hep Oil Company, Ltd. It has 7 wellbores on file with the Commission. Reported production runs from February 2003 to August 2026, totalling 191,709 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 $656K, with roughly $126K 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 181 barrels a month, about 26 per wellbore. Its strongest month on the record we hold was August 2017, at 642 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.
