Midland County · Dora Roberts (Consolidated) field · Producing · Vertical
Dora Roberts Ranch Unit #503 (API 42-329-10017) is a well in Midland County operated by Continental Resources Inc., completed January 1, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 21, 1984, permitted to 12,200 ft.
It was permitted by Cities Service Oil & Gas Corp. and has since transferred to Continental Resources Inc. on the wellbore schedule.
Completion filings report 8 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its 3 leases have reported 8.28M barrels of oil and 40.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 263 wells, so these are lease totals, not this well alone.
