Howard County · Howard-Glasscock (Glorieta) field · Vertical
Howard Glasscock East Unit #12 (API 42-227-30982) is a plugged well in Howard County, plugged May 19, 2014, last operated by Apache Corporation.
The RRC has issued one drilling permit, issued June 21, 1996, permitted to 3,000 ft.
It was permitted by Marathon Oil Company and has since transferred to Apache Corporation on the wellbore schedule.
Its 2 leases have reported 332K barrels of oil and 21.9K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 74 wells, so these are lease totals, not this well alone.
