University/Energen Grayburg Unit #1 (API 42-003-03121) is a plugged well in Andrews County, plugged June 23, 2006, last operated by Libertad Operating LLC.

The RRC has issued one drilling permit, issued October 13, 1998, permitted to 5,004 ft.

It was permitted by Taurus Exploration U.S.A., Inc. and has since transferred to Libertad Operating LLC on the wellbore schedule.

Its 3 leases have reported 919K barrels of oil and 15.3K mcf of gas since January 1993, last reporting in July 2026. The leases carry 35 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
