WESTBROOK SOUTHEAST UNIT
WESTBROOK SOUTHEAST UNIT is a Texas oil lease in Mitchell County, Railroad Commission district 08, operated by Fina Oil & Chemical Company. It has 633 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 17,499,147 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 $53.7M, with roughly $12.3M 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 17,196 barrels a month, about 27 per wellbore. Its strongest month on the record we hold was May 2016, at 34,882 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
