Midland County · Parks (Consolidated) field · Shut IN · Vertical
Parks Roy #4 (API 42-329-00840) is a well in Midland County operated by Cog Operating LLC, completed January 24, 1990 and listed as shut in on the RRC schedule, shut in April 1, 2024.
The RRC has issued 2 drilling permits between 1983 and 1989, permitted to 10,550 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Its 2 leases have reported 6.4M barrels of oil and 12.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 44 wells, so these are lease totals, not this well alone.
