WESTBROOK UNIT N
WESTBROOK UNIT N is a Texas oil lease in Cottle County, Railroad Commission district 8A, operated by Gunn Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from May 2016 to August 2026, totalling 129,089 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 $1.3M, with roughly $357K 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 578 barrels a month. Its strongest month on the record we hold was March 2017, at 2,571 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.
