Midland County · Parks (Spraberry) field · Vertical
Parks Roy #10 (API 42-329-00849) is a well in Midland County operated by Cog Operating LLC, completed October 3, 2004.
The RRC has issued one drilling permit, issued July 19, 2004, permitted to 10,375 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 6.4M barrels of oil and 12.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
