The RRC has issued 3 drilling permits between 1978 and 2005, permitted to 9,000 ft.
It was permitted by Exxon Mobil Corporation and has since transferred to Exxon Corp. on the wellbore schedule.

Its 4 leases have reported 3.92K barrels of oil and 1.39M mcf of gas since January 1993, last reporting in April 2010. The leases carry 5 wells, so these are lease totals, not this well alone.
