The RRC has issued one drilling permit, issued June 28, 1985, permitted to 10,100 ft.
It was permitted by L & B Oil CO. Inc. and has since transferred to Sundown Energy LP on the wellbore schedule.

Its 2 leases have reported 181 barrels of oil and 140K mcf of gas since January 1993, last reporting in October 2011. The leases carry 5 wells, so these are lease totals, not this well alone.
