Ohio-Sun Unit #8E
Matagorda County · Markham N.-Bay City N (7500 A) field · Shut In · Vertical
Ohio-Sun Unit #8E (API 42-321-00374) is a well in Matagorda County operated by Goldking Minerals Mgmt L.L.C., completed September 13, 2008 and listed as shut in on the RRC schedule, shut in January 1, 2000.
The RRC has issued 2 drilling permits between 1978 and 1980, permitted to 8,860 ft.
It was permitted by Marathon Oil Company and has since transferred to Goldking Minerals Mgmt L.L.C. on the wellbore schedule.
Its lease has reported 13 barrels of oil since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
Operator of record
