Estell Mary King #22 (API 42-355-00135) is a permitted well in Nueces County filed by Kamlok Oil & Gas, Inc.; no completion report is on file yet.
The RRC has issued 2 drilling permits between 1980 and 1995, permitted to 5,650 ft.
It was permitted by Kamlok Oil & Gas, Inc. and has since transferred to Durango Resources Corp. on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its 5 leases have reported 49.3K barrels of oil and 298K mcf of gas since January 1993, last reporting in July 2026. The leases carry 30 wells, so these are lease totals, not this well alone.
