O Connor Thomas -C- #8L
Refugio County · Tom Oconnor (5900 Sand) field · Shut In · Vertical
O Connor Thomas -C- #8L (API 42-391-01166) is a well in Refugio County operated by Hilcorp Energy Company, completed November 11, 1983 and listed as shut in on the RRC schedule, shut in September 1, 2021.
The RRC has issued one drilling permit, issued December 1, 1983, permitted to 5,916 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, Catahoua (Miocence), Anahuac.
Its 2 leases have reported 5.21M barrels of oil and 4.27M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 110 wells, so these are lease totals, not this well alone.
