Mitchell Estate #4 (API 42-239-02071) is a well in Jackson County operated by Mobil Oil Corporation, completed August 1, 1961.
The RRC has issued 2 drilling permits between 1979 and 2018, permitted to 5,927 ft.
It was permitted by Trinidad Resources, LLC and has since transferred to Mobil Oil Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Marginulina, Mitchell, Ward.
Its 2 leases have reported 1.37K barrels of oil and 1.48K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
