Dora Roberts Ranch Unit #4503 (API 42-329-00390) is a plugged well in Midland County, plugged July 6, 2026, last operated by Continental Resources Inc..
The RRC has issued 2 drilling permits between 1985 and 1986, permitted to 13,220 ft.
It was permitted by Cities Service Oil & Gas Corp. and has since transferred to Continental Resources Inc. on the wellbore schedule.
Its 3 leases have reported 1.08M barrels of oil and 4.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
