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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Wells named University 31-30

Red Stag Operating LLC's other wells filed under this lease name in Crockett County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

Chain of custody

Operator on the lease's P-4

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.
