Oconnor Thomas -A- #72 (API 42-391-01527) is a plugged well in Refugio County, plugged December 16, 2008, last operated by Hilcorp Energy Company.
The RRC has issued 2 drilling permits between 1979 and 1985, 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 6 formation tops, including Lagarto, Oakvvlle, 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.
