Refugio County · Mary Ellen Oconnor (H-117) field · Vertical
O Connor Thomas B #16 (API 42-391-01828) is a plugged well in Refugio County, plugged November 5, 2021, last operated by Hilcorp Energy Company.
The RRC has issued 2 drilling permits (amended once) between 1977 and 1992, permitted to 6,200 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 553K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
