University 40 #1506H (API 42-105-41572) is a plugged horizontal well in Crockett County, plugged January 17, 2024, last operated by Sem Operating Company LLC.
The RRC has issued one drilling permit, issued August 29, 2012, permitted to 6,520 ft.
It was permitted by Eog Resources, Inc. and has since transferred to Sem Operating Company LLC on the wellbore schedule.
Its lease has reported 5.89M barrels of oil and 91.5M mcf of gas since May 2010, last reporting volume in April 2026. The lease carries 64 wells, so these are lease totals, not this well alone.
