Obrien J. J. -B- #7 (API 42-391-31418) is a well in Refugio County operated by Greta Operating Company LLC, completed June 1, 1992 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 11, 1980, permitted to 4,500 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Greta Operating Company LLC on the wellbore schedule.
Completion filings report one formation top, including Grea (4400).
Its lease has reported 273K barrels of oil and 40.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
