Tom Oconnor (5800 SD) Fld. Unit #Q016 (API 42-391-01509) is a well in Refugio County operated by Hilcorp Energy Company, completed March 10, 1998 and listed as shut in on the RRC schedule, shut in September 1, 2022.

The RRC has issued 3 drilling permits between 1978 and 1998, permitted to 5,900 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 Frio, Lagarto, Oakville, Catahoula.

Its 3 leases have reported 23.4M barrels of oil and 15.8M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 633 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
