Oconnor Thomas -A- #79 (API 42-391-01759) is a well in Refugio County operated by Hilcorp Energy Company, completed April 23, 1981 and listed as shut in on the RRC schedule, shut in January 1, 1998.

The RRC has issued 2 drilling permits between 1981 and 1986, permitted to 5,925 ft.

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

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

Its lease has reported 650K barrels of oil and 756K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 36 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.
