Ohio-Sun Unit #29A (API 42-321-00065) is a well in Matagorda County operated by Goldking Minerals Mgmt L.L.C., completed December 19, 1996 and listed as not eligible for allowable on the RRC schedule, shut in April 1, 2000.

The RRC has issued one drilling permit, issued January 2, 1997, permitted to 8,516 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 223K barrels of oil and 543K 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.
