Cobb F. G. -B- #43 (API 42-321-31541) is a well in Matagorda County operated by Texian Operating Company LLC, completed October 2, 1987.
The RRC has issued 3 drilling permits between 1987 and 2005, permitted to 8,500 ft.
It was permitted by Apache Corporation and has since transferred to Texian Operating Company LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Fleming, Oakville, Anahuac.
Its 2 leases have reported 653K barrels of oil and 751K mcf of gas since January 1993, last reporting in July 2026. The leases carry 17 wells, so these are lease totals, not this well alone.
