Ward County · War-Wink S. (Wolfcamp) field · Producing · Horizontal
University 32-18 #4H (API 42-475-35352) is a horizontal well in Ward County operated by Apache Corporation, completed December 5, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 21, 2008, permitted to 11,600 ft.
It was permitted by Southwest Royalties, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 2 formation tops, including Bell Canyon, Bone Spring.
Its lease has reported 291K barrels of oil and 532K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
