Ohio-Sun Unit #6A (API 42-321-00051) is a plugged well in Matagorda County, plugged August 23, 2009, last operated by Premier Natural Resources LLC.

The RRC has issued 3 drilling permits between 1980 and 1994, permitted to 7,984 ft.

It was permitted by Marathon Oil Company and has since transferred to Premier Natural Resources LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Miocene (undifferentiated), Anahuac, Frio.

Its 2 leases have reported 223K barrels of oil and 370K mcf of gas since January 1993, last reporting in July 2026. The leases carry 22 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
