Schleicher County · Holt Ranch (Consolidated) field · Producing · Vertical
University 54-13 #2 (API 42-413-32774) is a well in Schleicher County operated by Zarvona Energy LLC, completed October 6, 2011 and listed as producing on the RRC schedule, shut in August 1, 2026.
The RRC has issued one drilling permit (amended once), issued September 12, 2011, permitted to 8,337 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 L5 Top, Dean, Wolfcamp.
Its 2 leases have reported 21.4K barrels of oil and 165K mcf of gas since December 2010, last reporting volume in February 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received Jan 7, 2015. Density, 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.
