Oconnor Thos. #11 (API 42-391-31482) is a well in Refugio County operated by Greta Operating Company LLC, completed March 5, 1982 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 9, 1981, permitted to 4,500 ft.

It was permitted by Amoco Production Company and has since transferred to Greta Operating Company LLC on the wellbore schedule.

Its lease has reported 147K barrels of oil and 51.5K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
