EXXON COWDEN "B"
EXXON COWDEN "B" is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Tamarack Petroleum Company, Inc. It has 4 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 197,909 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 $588K, with roughly $106K 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 135 barrels a month, about 34 per wellbore. Its strongest month on the record we hold was March 2021, at 1,159 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.
