The RRC has issued one drilling permit, issued May 29, 2003, permitted to 12,600 ft.
It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 2 leases have reported 384 barrels of oil and 465K mcf of gas since September 2003, last reporting volume in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
