G-M-K West Unit #112 (API 42-165-35971) is a well in Gaines County operated by Hilcorp Energy Company, completed July 29, 2003 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 11, 2003, permitted to 6,000 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 lease has reported 1.77M barrels of oil and 386K mcf of gas since December 2001, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 27.1K barrels injected in the 12 months reported through October 2025.
