University 31-30 #1 (API 42-105-34519) is a well in Crockett County operated by Red Stag Operating LLC, completed March 6, 1993 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1983 and 1992, permitted to 9,617 ft.
It was permitted by Thompson, J. Cleo and has since transferred to Red Stag Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including San Andres, Canyon, Strawn, Detrital.
Its 2 leases have reported 1.82K barrels of oil and 556K mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
