University 20-11 #1H (API 42-495-32413) is a plugged horizontal well in Winkler County, plugged February 19, 2004, last operated by O Neill Properties Ltd..
The RRC has issued 2 drilling permits between 1992 and 2010, permitted to 13,500 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to O Neill Properties Ltd. on the wellbore schedule.
Completion filings report 5 formation tops, including Cherry Canyon, Brushy Canyon, Bone Spring, Wolfcamp.
Its 2 leases have reported 391K barrels of oil and 341K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
