O Connor Thomas C #58 (API 42-391-01139) is a well in Refugio County operated by Hilcorp Energy Company, completed December 6, 1999 and listed as temp abandoned on the RRC schedule, shut in November 1, 2004.

The RRC has issued 2 drilling permits (amended once) between 1998 and 1999, permitted to 4,500 ft.

It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 6 formation tops, including Surface Sand Clay, Lagarto, Oakville, Catahoula.

Its 3 leases have reported 646K barrels of oil and 839K mcf of gas since January 1993, last reporting in July 2026. The leases carry 20 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.
