Oconnor Thomas -D- #C312 (API 42-391-02041) is a permitted well in Refugio County filed by Hilcorp Energy Company; no completion report is on file yet.

The RRC has issued 3 drilling permits between 1977 and 2011, permitted to 5,920 ft.

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

Completion filings report one formation top, including Frio.

Its 2 leases have reported 22.8M barrels of oil and 15.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 601 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.
