Oconnor Thomas -B- #C229 (API 42-391-01609) is a former disposal or injection well in Refugio County, last operated by T - C Oil Company; its UIC permit is no longer active.
The RRC has issued 2 drilling permits (amended once) between 1977 and 1986, permitted to 5,931 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to T - C Oil Company on the wellbore schedule.
Completion filings report 5 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.
Its lease has reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting in July 2026. The lease carries 594 wells, so these are lease totals, not this well alone.
Operator of record
