Oconnor Thos. #2
Refugio County · Greta (4400) field · Vertical
Oconnor Thos. #2 (API 42-391-00973) is a well in Refugio County operated by Greta Operating Company LLC, completed January 9, 1938.
The RRC has issued 2 drilling permits (amended twice) between 1991 and 2003, permitted to 6,100 ft.
It was permitted by Acock/Anaqua Operating CO., LP 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 425K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Acock/Anaqua Operating Co., LP; the EWA schedule now lists a different operator.
