University 7-3 #1 (API 42-317-35926) is a well in Martin County operated by Diamondback E&P LLC, completed September 28, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 13, 2010, permitted to 12,000 ft.

It was permitted by Opal Resources Operating CO.,LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 210K barrels of oil and 571K mcf of gas since July 2010, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
