University 40 #1101WD (API 42-235-34621) is a well in Irion County operated by Sem Operating Company LLC, completed May 28, 2011 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued December 13, 2010, permitted to 9,800 ft.

It was permitted by Eog Resources, Inc. and has since transferred to Sem Operating Company LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Wolfcamp, Strawn, Ellenburger.

Its lease has reported 5.89M barrels of oil and 91.5M mcf of gas since May 2010, last reporting in July 2026. The lease carries 64 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.
