Ward County · Phantom (Wolfcamp) field · Producing · Horizontal
Big Silver 34-160 #4H (API 42-475-36268) is a horizontal well in Ward County operated by Apache Corporation, completed January 10, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 17, 2012, permitted to 11,650 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Cherry Canyon, Brushy Canyon, Bone Spring, Wolfcamp.
Its lease has reported 772K barrels of oil and 1.35M mcf of gas since September 2012, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
