Ector County · Penwell field · Injection · Vertical
East Penwell /San Andres/ Unit #806 (API 42-135-05171) is a well in Ector County operated by Bce-Mach Iii LLC, completed September 17, 2004 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued August 20, 1990, permitted to 4,000 ft.
It was permitted by Fina Oil & Chemical Company and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Anhydrite, Yates, Grayburg, San Andres.
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 72K barrels injected in the 12 months reported through October 2025.
