Ward County · Phantom (Wolfcamp) field  · Horizontal

Effie Ponder Est. 33-18 #1H (API 42-475-30390) is a horizontal well in Ward County operated by Apache Corporation, completed January 26, 2008.

The RRC has issued 2 drilling permits (amended once) between 2007 and 2008, permitted to 15,265 ft.

It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report one formation top, including Bonesprings.

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.
