Tuscaloosa Marine Shale Geology

The Tuscaloosa Marine Shale is from the Cretaceous age. The Tuscaloosa Group is represented by three units with a marine shale that forms the middle unit. The midlle unit, the Tuscaloosa Marine Shale, is found at depths that vary from 9,000 to 14,000 ft, with a formation thickness from 500 ft to over 800 ft.

The Tuscaloosa Marine Shale is comprised of gray and black shale, with sand present in some areas. Generally, the formation gets thicker as you move down dip. The upper Tuscaloosa is a sand and clay formation, while the lower Tuscaloosa is also known as the Stringer Sands and Massive Sands formations.  A 1998 report by LSU’s Basin Research Institute estimated the Tuscaloosa Marine Shale might hold over 7 billion barrels of oil.
