South Fault Block Unit #12
Ector County · Andector (Ellenburger) field · Vertical
South Fault Block Unit #12 (API 42-135-02707) is a well in Ector County operated by Maverick Permian LLC, completed June 26, 1989.
The RRC has issued 2 drilling permits between 1998 and 2019, permitted to 9,000 ft.
It was permitted by Conocophillips Company and has since transferred to Maverick Permian LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Holt, Glorieta, Clear Fork, Clfk.
Its 2 leases have reported 4.13M barrels of oil and 3.56M mcf of gas since January 1993, last reporting in July 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
