Gutierrez J. M. #12 (API 42-505-34391) is a well in Zapata County operated by Hilcorp Energy Company, completed October 20, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 30, 2001, permitted to 10,300 ft.
It was permitted by Houston Exploration Company, The and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 919 barrels of oil and 4.11M mcf of gas since September 2001, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
