Effie Ponder Est. 33-18 #5H (API 42-475-37251) is a horizontal well in Ward County operated by Apache Corporation, completed July 11, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 14, 2017, permitted to 13,000 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 10 formation tops, including Clear Fork, Delaware, Glorieta, Holt.
Its lease has reported 1.25M barrels of oil and 1.41M mcf of gas since March 2008, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
