What is it about?
The Tuscaloosa Marine Shale (TMS) Formation is a clay- and organic-rich emerging shale play with a considerable amount of hydrocarbon resources. Despite its substantial potential, there have been only a few wells drilled and produced in the formation in recent years. Analyzed TMS samples contain an average of 50 wt% total clay, 27 wt% quartz, and 14 wt% calcite, and the mineralogy varies considerably over the small intervals. The high amount of clay leads to pronounced anisotropy, and the frequent changes in mineralogy result in the heterogeneity of the formation. We studied the compressional- (VP) and shear-wave (VS) velocities to evaluate the degree of anisotropy and heterogeneity, which impact hydraulic fracture growth, borehole instabilities, and subsurface imaging.

Why is it important?
The results provide further insights into TMS Formation evaluation and contribute to a better understanding of the heterogeneity and anisotropy of the play.
