Refugio County · Tom Oconnor (5450 Sand) field · Shut In · Vertical
Oconnor Thomas -A- #101 (API 42-391-01557) is a well in Refugio County operated by Hilcorp Energy Company, completed November 13, 2021 and listed as shut in on the RRC schedule, shut in December 1, 2021.
The RRC has issued 2 drilling permits between 1989 and 1996, permitted to 5,898 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 9 formation tops, including Lagarto, Surface, Sd & Clay, Oakville, Catahoula.
Its 2 leases have reported 776K barrels of oil and 1.31M mcf of gas since January 1993, last reporting in July 2026. The leases carry 40 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
