Tom O Connor (4150 FT. SD.) Unit #74 (API 42-391-00720) is a well in Refugio County operated by Hilcorp Energy Company, completed August 16, 1985 and listed as shut in on the RRC schedule, shut in June 1, 2009.

The RRC has issued one drilling permit, issued June 24, 1985, permitted to 4,452 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 Recent (Water Sands), Lagarta, Oakville, Catahoula.

Its 2 leases have reported 613K barrels of oil and 1.35M mcf of gas since January 1993, last reporting in July 2026. The leases carry 75 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.
