Refugio County · Tom Oconnor (5800) field · Shut In · Vertical
Tom Oconnor (5800 SD) Fld. Unit #39 (API 42-391-01463) is a well in Refugio County operated by Hilcorp Energy Company, completed August 12, 1991 and listed as shut in on the RRC schedule, shut in December 1, 2025.
The RRC has issued 3 drilling permits between 1979 and 1985, permitted to 5,919 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 2 leases have reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 594 wells, so these are lease totals, not this well alone.
