The RRC has issued one drilling permit, issued October 26, 2009, permitted to 4,968 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 50.3M barrels of oil and 202M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 412 wells, so these are lease totals, not this well alone.
