Ward County · War-Wink S. (Wolfcamp) field · Horizontal
University 22-18 -B- #1H (API 42-475-31567) is a plugged horizontal well in Ward County, plugged September 5, 2003, last operated by Texaco E & P Inc..
The RRC has issued 4 drilling permits (amended twice) between 1977 and 2008, permitted to 13,700 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Texaco E & P Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Delaware, Cherry Canyon, Bone Spring, War-Wink S. (Wolfcamp).
Its 4 leases have reported 435K barrels of oil and 572K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
