Tom Oconnor (5800 SD) Fld. Unit #P141 (API 42-391-30588) is a well in Refugio County operated by Hilcorp Energy Company, completed July 7, 1990 and listed as shut in on the RRC schedule, shut in December 1, 2025.

The RRC has issued 2 drilling permits between 1980 and 1990, permitted to 8,544 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 23.3M barrels of oil and 16.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 634 wells, so these are lease totals, not this well alone.
