Parks Field Unit #1 (API 42-329-01143) is a plugged well in Midland County, plugged April 1, 2020, last operated by Cog Operating LLC.
The RRC has issued 2 drilling permits between 1985 and 2007, permitted to 11,300 ft.
It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Pennsylvanian.
Its 3 leases have reported 17.6M barrels of oil and 45.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 174 wells, so these are lease totals, not this well alone.
