Ohio-Sun Unit #11E
Matagorda County · Markham N.-Bay City N (Hurd SD) field · Shut In · Vertical
Ohio-Sun Unit #11E (API 42-321-00129) is a well in Matagorda County operated by Goldking Minerals Mgmt L.L.C., completed February 29, 2000 and listed as shut in on the RRC schedule, shut in September 1, 2002.
The RRC has issued 2 drilling permits between 1981 and 2000, permitted to 8,900 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 755K barrels of oil and 499K mcf of gas since January 1993, last reporting in July 2026. The leases carry 28 wells, so these are lease totals, not this well alone.
