The RRC has issued 2 drilling permits between 2000 and 2002, permitted to 1,300 ft.
It was permitted by Polaris Production Corp. and has since transferred to 5stone Operating Inc on the wellbore schedule.

Its 2 leases have reported 24.7K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The leases carry 20 wells, so these are lease totals, not this well alone.
