The RRC has issued one drilling permit, issued April 30, 2018, permitted to 8,909 ft.
It was permitted by Parsley Energy Operations, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Its lease has reported 587K barrels of oil and 4.76M mcf of gas since December 2018, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
