Gaines County · G-M-K West (San Andres) field · Producing · Vertical
G-M-K West Unit #2 (API 42-165-35361) is a well in Gaines County operated by Hilcorp Energy Company, completed September 2, 1998 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 31, 1998, permitted to 5,750 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including Rustler, Yates, Grayburg, San Andres.
Its 2 leases have reported 2.16M barrels of oil and 444K mcf of gas since May 1998, last reporting volume in April 2026. The leases carry 27 wells, so these are lease totals, not this well alone.
