Cobb F. G. -B- #4
Matagorda County · Bay City (8200 Frio) field · Vertical
Cobb F. G. -B- #4 (API 42-321-00440) is a well in Matagorda County operated by Urban Oil & Gas Group LLC, completed October 18, 1982.
The RRC has issued 5 drilling permits between 1983 and 2005, permitted to 9,000 ft.
It was permitted by Apache Corporation and has since transferred to Urban Oil & Gas Group LLC on the wellbore schedule.
Its 5 leases have reported 751K barrels of oil and 1.06M mcf of gas since January 1993, last reporting in July 2026. The leases carry 37 wells, so these are lease totals, not this well alone.
