The RRC has issued one drilling permit, issued July 5, 2023, permitted to 9,918 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 2.77M barrels of oil and 8.77M mcf of gas since August 2023, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
