O Connor Thomas C #51 (API 42-391-01143) is a well in Refugio County operated by Hilcorp Energy Company, completed November 2, 2006 and listed as temp abandoned on the RRC schedule, shut in September 1, 2012.

The RRC has issued 5 drilling permits (amended twice) between 1996 and 2011, permitted to 5,915 ft.

Its 5 leases have reported 25.8M barrels of oil and 17.1M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 656 wells, so these are lease totals, not this well alone.
