Andrews County · Wemac South (Wolfcamp) field · Water Supply · Vertical
Wemac South (Wolfcamp) Unit #1 - WS (API 42-003-03946) is a well in Andrews County operated by Zarvona Energy LLC, completed March 1, 1978 and listed as water supply on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued December 2, 1977, permitted to 10,110 ft.
It was permitted by Amoco Production Company and has since transferred to Zarvona Energy LLC on the wellbore schedule.
Its lease has reported 73.4K barrels of oil and 25.5K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
