The RRC has issued one drilling permit, issued January 6, 2006, permitted to 8,500 ft.
It was permitted by Gruy Petroleum Management CO. and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Its 3 leases have reported 550K barrels of oil and 3.16M mcf of gas since January 1993, last reporting in July 2026. The leases carry 40 wells, so these are lease totals, not this well alone.
