Oconnor Thos. #1 (API 42-391-00972) is a well in Refugio County operated by Greta Operating Company LLC, completed May 15, 1989.
The RRC has issued 2 drilling permits between 1989 and 1990, permitted to 4,392 ft.
It was permitted by Chilton Energy and has since transferred to Greta Operating Company LLC on the wellbore schedule.
Completion filings report one formation top, including Greta.
Its 3 leases have reported 147K barrels of oil and 676K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
