South Fault Block Unit #462 (API 42-135-35951) is a plugged horizontal well in Ector County, plugged November 18, 2025, last operated by Maverick Permian LLC.
The RRC has issued 2 drilling permits between 1988 and 2001, permitted to 8,600 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Maverick Permian LLC on the wellbore schedule.
Completion filings report 6 formation tops, including San Andres, Glorieta, Clear Fork, Tubb.
Its lease has reported 4.13M barrels of oil and 3.32M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 45 wells, so these are lease totals, not this well alone.
