The RRC has issued 2 drilling permits between 2005 and 2018, permitted to 10,600 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 1.09M barrels of oil and 3.06M mcf of gas since May 2004, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
