Tom Oconnor (5800 SD) Fld. Unit #43U (API 42-391-00702) is a well in Refugio County operated by Hilcorp Energy Company, completed October 18, 1988 and listed as shut in on the RRC schedule, shut in December 1, 2024.
The RRC has issued one drilling permit, issued September 22, 1987, 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 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 volume in April 2026. The lease carries 594 wells, so these are lease totals, not this well alone.
