Irion County · Lin (Wolfcamp) field · Producing · Horizontal
University 43 #0902H (API 42-235-34711) is a horizontal well in Irion County operated by Sem Operating Company LLC, completed December 19, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 19, 2011, permitted to 6,714 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 2.37M barrels of oil and 39.8M mcf of gas since January 2011, last reporting volume in April 2026. The lease carries 30 wells, so these are lease totals, not this well alone.
