COLE RANCH -35-

COLE RANCH -35- is a Texas oil lease in Glasscock County, Railroad Commission district 08, operated by Energen Resources Corporation. It has 40 wellbores on file with the Commission. Reported production runs from July 2010 to August 2026, totalling 2,132,413 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 $12.6M, with roughly $3.8M 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 4,816 barrels a month, about 120 per wellbore. Its strongest month on the record we hold was May 2016, at 23,132 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
