Prideaux R.O. Unit #41 (API 42-503-35831) is a well in Young County operated by Kelly Mahler Operating LLC, completed March 18, 1982.
The RRC has issued one drilling permit, issued March 16, 1982, permitted to 800 ft.
It was permitted by Kunkel, Raylan and has since transferred to Kelly Mahler Operating LLC on the wellbore schedule.
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.
