The RRC has issued one drilling permit (amended twice), issued December 13, 2011, permitted to 10,717 ft.
It was permitted by Anadarko Petroleum Corporation and has since transferred to Anadarko E&P Onshore LLC on the wellbore schedule.

Its lease has reported 1.24M barrels of oil and 2.51M mcf of gas since May 2011, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
