University 45 #2207HB (API 42-105-42447) is a horizontal well in Crockett County operated by Zarvona Energy LLC, completed August 9, 2018 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 1, 2018, permitted to 7,800 ft.

It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Queen, San Andres, Leonard, Wolfcamp.

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