The RRC has issued one drilling permit, issued December 17, 1986, permitted to 600 ft.
It was permitted by Wilton, Frank and has since transferred to Mullin W. B. on the wellbore schedule.

Its 2 leases have reported 10.2K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
