Refugio County · Tom Oconnor (6600) field · Vertical
Oconnor Thomas C #Q279 (API 42-391-31248) is a well in Refugio County operated by Quintana Pet. Corp., completed February 15, 1985.
The RRC has issued 3 drilling permits between 1978 and 2024, permitted to 8,500 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Quintana Pet. Corp. on the wellbore schedule.
Completion filings report 5 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.
Its 3 leases have reported 28M barrels of oil and 19.2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 704 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Hilcorp Energy Company; the EWA schedule now lists a different operator.
