Tom O Connor (4150 FT. SD.) Unit #76 (API 42-391-03787) is a well in Refugio County operated by Hilcorp Energy Company, completed April 8, 1991 and listed as shut in on the RRC schedule, shut in June 1, 2015.

The RRC has issued one drilling permit, issued April 2, 1991, permitted to 4,515 ft.

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

Completion filings report 5 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 3 leases have reported 2.79M barrels of oil and 2.28M mcf of gas since January 1993, last reporting in July 2026. The leases carry 121 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.
