Ector County · Penwell field · Vertical

East Penwell /San Andres/ Unit #821W (API 42-135-38568) is a plugged well in Ector County, plugged August 15, 2024, last operated by Bce-Mach Iii LLC.

The RRC has issued one drilling permit, issued January 21, 2004, permitted to 4,500 ft.

It was permitted by Energen Resources Corporation and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Grayburg, San Andres, Zone 2, Zone 4.

Its lease has reported 13.6M barrels of oil and 1.37M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 377 wells, so these are lease totals, not this well alone.
