Tom Oconnor (5800 SD) Fld. Unit #C476 (API 42-391-32147) is a well in Refugio County operated by Hilcorp Energy Company, completed November 21, 1996 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 29, 1996, permitted to 6,200 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 lease has reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting in July 2026. The lease carries 594 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.
