Ohio-Sun Unit #6K
Matagorda County · Markham N.-Bay City N(cornelius) field · Shut In · Vertical
Ohio-Sun Unit #6K (API 42-321-02844) is a well in Matagorda County operated by Goldking Minerals Mgmt L.L.C., completed August 11, 1992 and listed as shut in on the RRC schedule, shut in March 1, 2019.
The RRC has issued 2 drilling permits between 1986 and 1992, permitted to 8,800 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 3 formation tops, including Miocene (undifferentiated), Anahuac, Frio.
Its 2 leases have reported 1.8M barrels of oil and 1.71M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 80 wells, so these are lease totals, not this well alone.
