University 45 #1 (API 42-105-41015) is a well in Crockett County operated by Zarvona Energy LLC, completed December 1, 2009.
The RRC has issued one drilling permit (amended once), issued October 13, 2009, permitted to 9,000 ft.
It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Base Cretaceous (marker), Dean, Canyon.
Its 4 leases have reported 6.72M barrels of oil and 79.9M mcf of gas since December 2009, last reporting in July 2026. The leases carry 108 wells, so these are lease totals, not this well alone.
