University-AI #18 (API 42-461-31155) is a well in Upton County operated by Q Natural Resources LLC, completed August 11, 1977 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued June 8, 1977, permitted to 4,100 ft.

It was permitted by Aminoil USA Inc. and has since transferred to Q Natural Resources LLC on the wellbore schedule.

Its lease has reported 277K barrels of oil and 206K mcf of gas since January 1993, last reporting in July 2026. The lease carries 27 wells, so these are lease totals, not this well alone.
