The RRC has issued one drilling permit, issued February 19, 1998, permitted to 2,900 ft.
It was permitted by Oryx Energy Company and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Its 2 leases have reported 2.84M barrels of oil and 751 mcf of gas since January 1993, last reporting in July 2026. The leases carry 168 wells, so these are lease totals, not this well alone.
