Refugio County · Tom Oconnor (5800) field · Shut In · Vertical
Tom Oconnor (5800 SD) Fld. Unit #Q041 (API 42-391-01466) is a well in Refugio County operated by Hilcorp Energy Company, completed January 19, 2023 and listed as shut in on the RRC schedule, shut in January 1, 2023.
The RRC has issued 2 drilling permits between 1995 and 1997, permitted to 5,896 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, Catahould (Miocene).
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 595 wells, so these are lease totals, not this well alone.
