The RRC has issued one drilling permit, issued September 25, 2000, permitted to 11,500 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 521K barrels of oil and 2.46M mcf of gas since April 2001, last reporting volume in August 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
