The RRC has issued one drilling permit, issued May 4, 2015, permitted to 7,800 ft.
It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.

Its lease has reported 1.66M barrels of oil and 19M mcf of gas since September 2010, last reporting in July 2026. The lease carries 71 wells, so these are lease totals, not this well alone.
