Refugio County · Tom O Connor (5600 Foot Sand) field · Shut In · Vertical
Tom O Connor(5600 Foot Sand)Unit #19 (API 42-391-31900) is a well in Refugio County operated by Hilcorp Energy Company, completed October 17, 2011 and listed as shut in on the RRC schedule, shut in June 1, 2019.
The RRC has issued 3 drilling permits between 1985 and 1999, permitted to 6,100 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 8 formation tops, including Lagarto, Surface Sand Clay, Oakville, Catahoula.
Its 5 leases have reported 24.5M barrels of oil and 15.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 679 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
