The RRC has issued one drilling permit (amended once), issued June 25, 2020, permitted to 12,500 ft.
It was permitted by Diamondback E&P LLC and has since transferred to Trp Operating LLC on the wellbore schedule.

Its lease has reported 798K barrels of oil and 6.57M mcf of gas since February 2020, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
