Tom Oconnor (5800 SD) Fld. Unit #13 (API 42-391-00473) is a permitted well in Refugio County filed by Quintana Pet. Corp.; no completion report is on file yet.

The RRC has issued 2 drilling permits between 1999 and 2000, permitted to 5,935 ft.

It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 7 formation tops, including Surface Sand Clay, Largarito, Oakville, Catahoula.

Its 4 leases have reported 24M barrels of oil and 16.1M mcf of gas since January 1993, last reporting in July 2026. The leases carry 668 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.
