Estell Mary King #217
Nueces County · Richard King (5600 Upper) field · Vertical
Estell Mary King #217 (API 42-355-00150) is a well in Nueces County operated by Durango Resources Corp., completed January 24, 1978.
The RRC has issued 2 drilling permits (amended once) between 1977 and 1990, 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 3 formation tops, including Miocene (undifferentiated), Catahoula, Vicksburg.
Its 2 leases have reported 2.57K barrels of oil and 2.13K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
