Dora Roberts Ranch Unit #4218 (API 42-329-30811) is a well in Midland County operated by Continental Resources Inc., completed November 1, 1978 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 17, 1978, permitted to 12,920 ft.
It was permitted by Cities Service Company and has since transferred to Continental Resources Inc. on the wellbore schedule.
Its lease has reported 809K barrels of oil and 5.29M mcf of gas since January 1993, last reporting in July 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
