The RRC has issued one drilling permit, issued November 24, 1980, permitted to 8,500 ft.
It was permitted by Palo Petroleum, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Its lease has reported 20.9K barrels of oil and 41K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
