The RRC has issued one drilling permit (amended once), issued July 7, 2017, permitted to 11,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 498K barrels of oil and 3.52M mcf of gas since February 2018, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
