Tom Oconnor (5800 SD) Fld. Unit #Q328 (API 42-391-00694) is a plugged well in Refugio County, plugged April 13, 2020, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit (amended once), issued September 21, 1993, 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 7 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 2 leases have reported 24.4M barrels of oil and 16.6M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 637 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.
