Tom Oconnor (5800 SD) Fld. Unit #54U (API 42-391-01470) is a well in Refugio County operated by Hilcorp Energy Company, completed April 13, 2021 and listed as shut in on the RRC schedule, shut in March 1, 2024.

The RRC has issued one drilling permit (amended once), issued August 22, 1984, permitted to 5,925 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 Lagarto, Oakville, Catahoula, Anahuac.

Its 3 leases have reported 24M barrels of oil and 16.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 658 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
