Westbrook Southeast Unit #531
Mitchell County · Westbrook (Clear Fork Upper) field · Producing · Vertical
Westbrook Southeast Unit #531 (API 42-335-31959) is a well in Mitchell County operated by Bce-Mach Iii LLC, completed October 1, 2014 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1981 and 2014, permitted to 3,200 ft.
It was permitted by Energen Resources Corporation and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Completion filings report one formation top, including Clear Fork.
Its 2 leases have reported 17.5M barrels of oil and 971K mcf of gas since January 1993, last reporting in July 2026. The leases carry 640 wells, so these are lease totals, not this well alone.
