University 54 23 #2 (API 42-413-32765) is a well in Schleicher County operated by Upp Operating LLC, completed December 22, 2011.

The RRC has issued one drilling permit (amended once), issued July 15, 2011, permitted to 8,500 ft.

It was permitted by Highmount Expl & Prod Texas LLC and has since transferred to Upp Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Base Cretaceous (marker), Leonard, Wolfcamp, Canyon.

Its 2 leases have reported 5.91K barrels of oil and 47.5K mcf of gas since December 2011, last reporting in July 2026. The leases carry 3 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.
