Abstract. Virtually every sandstone reservoir contains significant amounts of shale. Although the sand/shale sequence in the wells may be known, a reliable reservoir description must define quantitatively the lateral continuity of the shale, the shale distribution in unsampled areas, and the effects of the shales on transport properties.Shale rock is a type of clastic sedimentary rock composed of fine mud or clay minerals in flakes and tiny fragments. Clastic sedimentary rocks are rocks that form from …(2003) Stratigraphy of the Upper Cretaceous Mancos. Shale (upper part) and Mesaverde Group in the southern part of the Uinta and Piceance basins,.

Crystal sizes given in millimeters (mm) are preferred rather than fractional inch (in) equivalents. Definition: The term shale is often used as a very general term for all kinds of clay rich sedimentary rocks. Shales are the most abundant kind of all sedimentary rocks accounting for around 60% of the stratigraphic column. As such, most of the time spent drilling oil wells is spent drilling through shales. Clay minerals account for about 50-60 ...Layering, or bedding, is the most obvious feature of sedimentary rocks. Sedimentary rocks are formed particle by particle and bed by bed, and the layers are piled one on top of the other. Thus, in any sequence of layered rocks, a given bed must be older than any bed on top of it. This Law of Superposition is fundamental to the interpretation of ...Comprehensive research has shown that fine-detailed identification and description of lacustrine shale lithofacies is an important task for shale oil and gas exploration and development evaluation.
