The RRC has issued one drilling permit (amended once), issued May 14, 2020, permitted to 9,000 ft.
It was permitted by De3 Operating LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Its lease has reported 473K barrels of oil and 1.22M mcf of gas since August 2020, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
