Young County · Young County Regular field · Vertical
Prideaux R. O. Unit #8D (API 42-503-40254) is a well in Young County operated by Stewart Construction, completed February 8, 1991.
The RRC has issued one drilling permit, issued November 8, 1990, permitted to 1,000 ft.
It was permitted by Peterson & Roberts and has since transferred to Stewart Construction on the wellbore schedule.
Completion filings report one formation top, including Hard Lime.
Its 2 leases have reported 82.2K barrels of oil and 104 mcf of gas since January 1993, last reporting in July 2026. The leases carry 56 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 3.75K barrels injected in the 12 months reported through November 2025.
Operator of record
