Gaines County · G-M-K (San Andres) field · Shut In · Vertical
G-M-K /San Andres/ Unit #721 (API 42-165-35815) is a well in Gaines County operated by Hilcorp Energy Company, completed June 4, 2002 and listed as shut in on the RRC schedule, shut in January 1, 2017.
The RRC has issued one drilling permit, issued March 12, 2002, permitted to 5,765 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Grayburg, San Andres, Pi Marker.
Its lease has reported 5.4M barrels of oil and 1.7M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 86 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
