Oconnor Dennis Etal -L- #L 11 (API 42-391-00338) is a plugged well in Refugio County, plugged December 15, 2021, last operated by T-C Oil Company LLC.

The RRC has issued 4 drilling permits between 1979 and 2005, permitted to 4,649 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 5 formation tops, including Lagarto, Eocene, Miocene (undifferentiated), Catahoula.

Its 2 leases have reported 3.49M barrels of oil and 48.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 82 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.
