University -AU- #4 (API 42-461-33291) is a well in Upton County operated by Civitas Permian Operating LLC, completed August 26, 1992.
The RRC has issued 2 drilling permits (amended once) between 1992 and 2011, permitted to 10,300 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Yates, Queen, San Andres, Spraberry.
Its 2 leases have reported 73.4K barrels of oil and 419K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
