The RRC has issued one drilling permit, issued August 9, 2021, permitted to 11,000 ft.
It was permitted by Cog Operating LLC and has since transferred to Scout Energy Management LLC on the wellbore schedule.

Its lease has reported 1.94M barrels of oil and 3.23M mcf of gas since April 2022, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
