The RRC has issued one drilling permit, issued December 20, 2012, permitted to 9,885 ft.
It was permitted by Murphy Expl. & Prod. CO. - USA and has since transferred to Castlerock EF Operating LLC on the wellbore schedule.

Its lease has reported 3.77M barrels of oil and 5.35M mcf of gas since July 2011, last reporting in July 2026. The lease carries 32 wells, so these are lease totals, not this well alone.
