Refugio County · Mary Ellen Oconnor (FQ- 9) field · Vertical
O Connor Thos. -B- #18 (API 42-391-01830) is a plugged well in Refugio County, plugged August 17, 2018, last operated by Hilcorp Energy Company.
The RRC has issued 3 drilling permits (amended once) between 1979 and 1990, permitted to 6,118 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 2 leases have reported 53.5K barrels of oil and 308K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
