Oconnor Thomas -E- #C426 (API 42-391-01650) is a permitted well in Refugio County filed by Quintana Pet. Corp.; no completion report is on file yet.

The RRC has issued one drilling permit, issued July 7, 1995, permitted to 6,027 ft.

It was permitted by Quintana Pet. Corp. and has since transferred to T - C Oil Company on the wellbore schedule.

Completion filings report 5 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 2 leases have reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 597 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.
