Irion County · Lin (Wolfcamp) field · Producing · Horizontal
University 40 #1309H (API 42-235-34704) is a horizontal well in Irion County operated by Sem Operating Company LLC, completed March 13, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 18, 2011, permitted to 6,645 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 Spraberry, Dean, Wolfcamp.
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.

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