Tom Oconnor (5800 SD) Fld. Unit #P041 (API 42-391-01426) is a well in Refugio County operated by Hilcorp Energy Company, completed November 21, 2000 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 11, 1999, permitted to 5,900 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, Lagarto, Oakville, Catahoula.

Its 2 leases have reported 23.3M barrels of oil and 16.5M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 634 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.
