The RRC has issued one drilling permit (amended 3 times), issued September 8, 2017, permitted to 11,165 ft.
It was permitted by Ajax Resources, LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 1.46M barrels of oil and 1.32M mcf of gas since March 2018, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
