West San Andres Unit #28 (API 42-501-33523) is a plugged well in Yoakum County, plugged March 10, 2025, last operated by Riley Permian Operating CO LLC.
The RRC has issued one drilling permit, issued September 28, 1989, permitted to 5,500 ft.
It was permitted by Greenhill Petroleum Corporation and has since transferred to Riley Permian Operating CO LLC on the wellbore schedule.
Its 2 leases have reported 1.21M barrels of oil and 1.97M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 60 wells, so these are lease totals, not this well alone.
