Tom Oconnor (5800 SD) Fld. Unit #3115Q (API 42-391-32005) is a well in Refugio County operated by Hilcorp Energy Company, completed March 16, 2020 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued November 20, 1989, permitted to 6,000 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 Lagarto, Oakville, Catahoula, Anahuac.

Its lease has reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting in July 2026. The lease carries 594 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 724K barrels injected in the 12 months reported through September 2025.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
