Westbrook Southeast Unit #1854W (API 42-335-34220) is a well in Mitchell County operated by Bce-Mach Iii LLC, completed July 17, 2010 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued March 19, 2001, permitted to 3,200 ft.

It was permitted by First Permian, L.L.C. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its lease has reported 17.5M barrels of oil and 969K mcf of gas since January 1993, last reporting in July 2026. The lease carries 632 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 21.4K barrels injected in the 12 months reported through January 2026.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
