Oconnor Thomas -A- #104 (API 42-391-02035) is a plugged well in Refugio County, plugged December 4, 2013, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued June 8, 1977, permitted to 5,893 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 151K barrels of oil and 150K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
