Geological map including the Tuscaloosa Marine Shale

The Tuscaloosa Marine Shale is a 90-million-year-old Late Cretaceous sedimentary rock formation across the Gulf Coast region of the United States.[1]

It is similar in composition and

Eagle Ford Shale formation in southern Texas.[2]

The thickness of the formation varies from 500–800 feet,[3] and is located at a depth of 11,000-15,000 feet.

Petroleum

The formation is an

hydraulic fracturing (fracking) technologies to reach economic viability for extraction. The potential reserve is currently estimated at 7 billion barrels of oil.[4]
