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 2.1M barrels of oil and 10.9M mcf of gas since June 2013, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
