O Conner -D- #D 35 (API 42-391-31449) is a plugged well in Refugio County, plugged August 19, 2024, last operated by T-C Oil Company LLC.

The RRC has issued 4 drilling permits between 1981 and 1995, permitted to 8,000 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 134K barrels of oil and 807K mcf of gas since January 1993, last reporting in July 2026. The leases carry 14 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.
