Matagorda County · Bay City (7700 Frio) field · Vertical
Cobb F. G. -B- #39A (API 42-321-00450) is a well in Matagorda County operated by Texian Operating Company LLC, completed June 6, 1976.
The RRC has issued 6 drilling permits between 1983 and 2004, permitted to 11,000 ft.
It was permitted by Apache Corporation and has since transferred to Texian Operating Company LLC on the wellbore schedule.
Its 5 leases have reported 62.6K barrels of oil and 164K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Apache Corporation; the EWA schedule now lists a different operator.
