COLE, DORIS CHALK
COLE, DORIS CHALK is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Phillips Petroleum Company. It has 2 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 70,682 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 $368K, with roughly $61K 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 53 barrels a month, about 26 per wellbore. Its strongest month on the record we hold was March 2019, at 99 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.
