Ancell M #4 (API 42-487-31511) is a well in Wilbarger County operated by Quatro Oil And Gas Inc., completed October 16, 1981 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 8, 1981, permitted to 4,500 ft.
It was permitted by Ellis, Ken Oil CO. and has since transferred to Quatro Oil And Gas Inc. on the wellbore schedule.
Its lease has reported 8.73K barrels of oil and 477 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
