Dora Roberts Ranch Devonian Unit #4210 (API 42-329-00301) is a well in Midland County operated by Continental Resources Inc., completed May 2, 1991 and listed as prod factor well on the RRC schedule.

The RRC has issued 2 drilling permits between 1984 and 1991, permitted to 11,925 ft.

It was permitted by Oxy USA Inc. and has since transferred to Continental Resources Inc. on the wellbore schedule.

Completion filings report one formation top, including Pennsylvanian.

Its 2 leases have reported 26.2K barrels of oil and 837K mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
