The RRC has issued 3 drilling permits (amended twice) between 1984 and 2017, permitted to 11,400 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 133K barrels of oil and 214K mcf of gas since April 1999, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
