O Connor Thomas B #10 (API 42-391-01822) is a plugged well in Refugio County, plugged August 31, 2021, last operated by Hilcorp Energy Company.

The RRC has issued 5 drilling permits (amended once) between 1980 and 1992, permitted to 6,230 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, Catahoula, Anahuac.

Its 2 leases have reported 8.32K barrels of oil and 74.3K mcf of gas since January 1993, last reporting in October 2021. The leases carry 3 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.
