University -O- #12 (API 42-105-35122) is a plugged well in Crockett County, plugged November 11, 2011, last operated by R2q Operating LLC.
The RRC has issued one drilling permit, issued September 16, 1985, permitted to 2,700 ft.
It was permitted by Marathon Oil Company and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Yates, Seven Rivers, Queen, San Andres.
Its lease has reported 165K barrels of oil and 583K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
