Ward County · War-Wink W. (Wolfcamp) field · Producing · Horizontal
Warwink University 18-35 B #2H (API 42-475-34536) is a horizontal well in Ward County operated by Apache Corporation, completed November 19, 2006 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1997 and 2006, permitted to 11,720 ft.
It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, T/Salt, B/Salt, T/Delaware.
Its lease has reported 842K barrels of oil and 1.27M mcf of gas since February 1998, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
