Obrien J. J. -A- #2 (API 42-391-00777) is a plugged well in Refugio County, plugged October 7, 2022, last operated by Greta Operating Company LLC.
The RRC has issued 2 drilling permits in 1993, permitted to 2,380 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 124K barrels of oil and 270K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
