The RRC has issued one drilling permit, issued June 6, 1996, permitted to 5,450 ft.
It was permitted by Pennzoil Exploration & Prod. CO. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.
Its 2 leases have reported 49.8K barrels of oil and 404K mcf of gas since January 1993, last reporting in December 2015. The leases carry 3 wells, so these are lease totals, not this well alone.
