Tuscaloosa Marine Shale Geology

The Tuscaloosa Marine Shale is from the Cretaceous age, where the middle member marine shale is the target of exploratory drilling. The Tuscaloosa formation is defined by three separate stratigraphic units. The middle unit is predominately shale and found at depths that vary from 9,000 to 14,000 ft, with a formation thickness of 500 to 800 ft.

The gray and black shale of the Tuscaloosa Marine formation provide the high levels of organic content needed to make shale plays attractive. In certain areas of the play, sands are also present in the middle member of the Tuscaloosa Marine formation. As you move down dip in the trend, the middle member of the play gets thicker. The upper Tuscaloosa is characterized by its sand and clay content, while the lower member of the formation produces from conventional zones sometimes referred to as the Stringer Sand and the Massive Sand formations. The Tuscaloosa Marine Shale formation is estimated to hold over 7 billion barrels of oil (source: LSU Basin Research Institute)
