Oconnor -D- #D 36 (API 42-391-31448) is a plugged well in Refugio County, plugged April 27, 2011, last operated by T-C Oil Company LLC.
The RRC has issued 2 drilling permits between 1981 and 2004, permitted to 7,900 ft.
It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.
Its 2 leases have reported 1.36M barrels of oil and 5.95M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 26 wells, so these are lease totals, not this well alone.
