The RRC has issued one drilling permit (amended once), issued October 20, 2015, permitted to 14,500 ft.
It was permitted by Callon Petroleum Operating CO and has since transferred to Apache Corporation on the wellbore schedule.

Its lease has reported 2.72M barrels of oil and 9.66M mcf of gas since May 2008, last reporting volume in April 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
