University/Energen Grayburg Unit #1 (API 42-003-38483) is a plugged well in Andrews County, plugged June 27, 2006, last operated by Libertad Operating LLC.
The RRC has issued one drilling permit (amended once), issued April 21, 1999, permitted to 5,000 ft.
It was permitted by Energen Resources Corporation and has since transferred to Libertad Operating LLC on the wellbore schedule.
Its 2 leases have reported 919K barrels of oil since July 1999, last reporting in July 2026. The leases carry 34 wells, so these are lease totals, not this well alone.
