Winchester 34-142 #4H (API 42-475-36561) is a horizontal well in Ward County operated by Apache Corporation, completed February 11, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 6, 2013, permitted to 10,975 ft.

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

Completion filings report 2 formation tops, including Lamar, Bone Spring.

Its 2 leases have reported 215K barrels of oil and 689K mcf of gas since October 2013, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
