Reeves County · Wolfbone (Trend Area) field · Producing · Horizontal
The Great Milenko Unit 15-16 #10H (API 42-389-39608) is a horizontal well in Reeves County operated by Apache Corporation, completed August 2, 2022 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 9, 2021, permitted to 13,000 ft.
It was permitted by Primexx Operating Corporation and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 8 formation tops, including Castile, Delaware, Bell Canyon, Cherry Canyon.
Its lease has reported 1.03M barrels of oil and 4.61M mcf of gas since December 2021, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
