University C #1 (API 42-105-36836) is a well in Crockett County operated by Rim Operating Inc., completed May 5, 1995.
The RRC has issued one drilling permit (amended once), issued March 1, 1995, permitted to 8,600 ft.
It was permitted by R K Petroleum Corporation and has since transferred to Rim Operating Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Andover Spra. Zone, Spraberry, Dean, Wolfcamp.
Its 3 leases have reported 6.03K barrels of oil and 135K mcf of gas since May 1995, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
