The RRC has issued one drilling permit, issued September 13, 2013, permitted to 11,226 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 872K barrels of oil and 3.15M mcf of gas since August 2011, last reporting in July 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
