The RRC has issued one drilling permit, issued July 1, 1997, permitted to 11,200 ft.
It was permitted by Esenjay Petroleum Corp. and has since transferred to Esenjay Exploration Inc on the wellbore schedule.
Its 2 leases have reported 30.8K barrels of oil and 457K mcf of gas since September 1997, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
