University 52-23 #4H (API 42-105-41650) is a horizontal well in Crockett County operated by Permian Resources Operating LLC, completed March 3, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 30, 2012, permitted to 6,122 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Permian Resources Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its 2 leases have reported 686K barrels of oil and 14.5M mcf of gas since January 2013, last reporting volume in April 2026. The leases carry 22 wells, so these are lease totals, not this well alone.
