Estell Mary King #221
Nueces County · Richard King (Frio Cons.) field · Shut In · Vertical
Estell Mary King #221 (API 42-355-00154) is a well in Nueces County operated by Aransas Operating Company LLC, completed October 21, 1981 and listed as shut in on the RRC schedule, shut in December 1, 2008.
The RRC has issued 2 drilling permits between 1979 and 1981, permitted to 5,657 ft.
It was permitted by Sun Expl. & Prod. CO.-Houston and has since transferred to Aransas Operating Company LLC on the wellbore schedule.
Its 2 leases have reported 49.4K barrels of oil and 51K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 28 wells, so these are lease totals, not this well alone.
Operator of record
