University 45 #2
Crockett County · Holt Ranch (Consolidated) field · Shut In · Vertical
University 45 #2 (API 42-105-41285) is a well in Crockett County operated by Zarvona Energy LLC, completed November 30, 2011 and listed as shut in on the RRC schedule, shut in November 1, 2019.
The RRC has issued one drilling permit, issued May 16, 2011, permitted to 9,778 ft.
It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.
Completion filings report 4 formation tops, including San Andres, Clear Fork, Ozona Ne Canyon, Ellenburger.
Its 2 leases have reported 6.96M barrels of oil and 80.4M mcf of gas since June 2011, last reporting volume in March 2026. The leases carry 112 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.

Well logs
4 logs loaded from the RRC's log index, the latest received Aug 22, 2019. Density, Gamma ray, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
