University -X- #6 (API 42-105-35373) is a well in Crockett County operated by R2q Operating LLC, completed July 29, 1987 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 28, 1987, permitted to 2,708 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 133K barrels of oil and 388K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
