The RRC has issued one drilling permit (amended once), issued November 15, 2018, permitted to 12,000 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 3.11M barrels of oil and 8.53M mcf of gas since June 2019, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
