Oconnor Thomas -A- #27 (API 42-391-01542) is a well in Refugio County operated by Hilcorp Energy Company, completed May 23, 2000 and listed as shut in on the RRC schedule, shut in December 1, 2010.

The RRC has issued one drilling permit, issued September 29, 1999, permitted to 5,889 ft.

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

Completion filings report 6 formation tops, including Surface Sand Clay, Anahuac, Lagarto, Oakville.

Its 2 leases have reported 23.4M barrels of oil and 15.7M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 630 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.
