East Penwell /San Andres/ Unit #1218W (API 42-135-38570) is a well in Ector County operated by Bce-Mach Iii LLC, completed August 29, 2014 and listed as injection on the RRC schedule.

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 in July 2026. The lease carries 377 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 87.4K barrels injected in the 12 months reported through October 2025.

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