COOK UNIT III LAS
COOK UNIT III LAS is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Chesapeake Operating, L.L.C. It has 3 wellbores on file with the Commission. Reported production runs from December 2014 to August 2026, totalling 617,254 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 $3.2M, with roughly $799K 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 1,220 barrels a month, about 407 per wellbore. Its strongest month on the record we hold was June 2016, at 8,524 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.
