State Walton -E- A/C 4 #21 (API 42-495-02920) is a well in Winkler County operated by Mobil Oil Corporation, completed January 1, 1971.
The RRC has issued one drilling permit, issued November 4, 1999, permitted to 10,680 ft.
It was permitted by Prize Operating Company and has since transferred to Mobil Oil Corporation on the wellbore schedule.
Its 2 leases have reported 71K barrels of oil and 1.29M mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
