Mitchell County · Westbrook field · Producing · Vertical
Westbrook Southeast Unit #1868 (API 42-335-35054) is a well in Mitchell County operated by Bce-Mach Iii LLC, completed September 17, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 14, 2008, permitted to 3,344 ft.
It was permitted by Energen Resources Corporation and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Queen, Clear Fork.
Its lease has reported 17.5M barrels of oil and 969K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 632 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 23, 2009. Density, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
