The RRC has issued one drilling permit, issued November 18, 2024, permitted to 8,975 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 145K barrels of oil and 148K mcf of gas since January 2025, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
