The RRC has issued 2 drilling permits between 2001 and 2002, permitted to 8,521 ft.
It was permitted by Marathon Oil Company and has since transferred to Goldking Minerals Mgmt L.L.C. on the wellbore schedule.
Completion filings report 8 formation tops, including Markham, (Choate 7100), Markham, N-Bay City, N, Markham,N-Bay City,N(Carlson), (Choate 7100).
Its 3 leases have reported 223K barrels of oil and 363K mcf of gas since January 1993, last reporting volume in January 2025. The leases carry 23 wells, so these are lease totals, not this well alone.
