The RRC has issued one drilling permit, issued April 13, 2011, permitted to 3,200 ft.
It was permitted by Maverick Energy Group, Inc. and has since transferred to U.S. Jimoil Corporation on the wellbore schedule.

Its 3 leases have reported 5.82K barrels of oil and 3.61K mcf of gas since January 1993, last reporting in July 2026. The leases carry 97 wells, so these are lease totals, not this well alone.
