University 45 #933HA (API 42-105-41756) is a horizontal well in Crockett County operated by Zarvona Energy LLC, completed August 29, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 3, 2013, permitted to 6,946 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, Dean, Wolfcamp.

Its lease has reported 6.71M barrels of oil and 79.8M mcf of gas since August 2011, last reporting volume in March 2026. The lease carries 104 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Dec 17, 2018. Mud log. 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.
