Oconnor Thomas -C- #41 (API 42-391-01571) is a former disposal or injection well in Refugio County, last operated by Quintana Pet. Corp.; its UIC permit is no longer active.
The RRC has issued 3 drilling permits (amended once) between 2008 and 2017, permitted to 5,925 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Quintana Pet. Corp. on the wellbore schedule.
Completion filings report 4 formation tops, including Catahoula, Frio, Jackson, No Change.
Its 3 leases have reported 73.3K barrels of oil and 94.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 14 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Hilcorp Energy Company; the EWA schedule now lists a different operator.
