O Connor Thomas -C- #35 (API 42-391-01149) is a former disposal or injection well in Refugio County, last operated by Hilcorp Energy Company; its UIC permit is no longer active.

The RRC has issued 3 drilling permits between 1991 and 2013, permitted to 5,925 ft.

Completion filings report 9 formation tops, including Surface Sand And Clay, Lagarto, Oakville, Catahoula.

Its 6 leases have reported 27.2M barrels of oil and 17.6M mcf of gas since January 1993, last reporting in July 2026. The leases carry 745 wells, so these are lease totals, not this well alone.
