T-C Oil CO.- O Connor #11 (API 42-391-00265) is a plugged well in Refugio County, plugged June 14, 2011, last operated by T-C Oil Company LLC.

The RRC has issued 5 drilling permits between 1979 and 1993, permitted to 6,200 ft.

It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Lagarto, Eocene, Miocene (undifferentiated), Catahoula.

Its 3 leases have reported 6.52M barrels of oil and 31.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 115 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.
