Shale, formed largely from clay, is the most common sedimentary rock. [9] Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy.Matthew Bernstein, senior shale analyst at Rystad Energy, said in a note about Exxon’s acquisition that the deal could usher in a new "Shale 4.0" era, marking a …Mowry Shale- Black to gray, siliceous, fissile shale and siltstone containing bentonite layers, and sparse sandstone dikes and sills. Thickness 125-250 ft (38-76 m). Newcastle Sandstone- Gray, light-brown to yellow, discontinuously distributed siltstone, claystone, sandy shale, and fine-grained sandstone. Thickness up to 290 ft (88 m).Scanning electron micrographs of several shales indicate that the shale rocks are comprised of stacks of locally aligned clay platelets (Hornby et al., 1994; Sayers & den Boer, 2019). The stacks are often called domains (Aylmore & Quirk, 1960 ), and this local alignment is a key source of shale anisotropy (Sayers & den Boer, 2019 ).

Shale gas reservoirs contain a large number of natural fractures. When shear slip occurs during hydraulic fracturing, it will increase reservoir permeability and improve the reservoir stimulation performance. Because shale contains a large amount of clay and organic matter, its shear slip behavior differs from that of other rocks.

Clay minerals are abundant in shale, characterized by a lamellar structure and dimensions smaller than a micron, giving rise to nanometer-scale pore size and large specific surface area (Rotenberg, 2014). Organic matter (OM) is also a major component of shale, where majority of the gas/oil is generated and stored.

Shales are loose, plastic, fine-grained mixtures of clay-sized particles or colloidal-sized particles and often contain a high proportion of clay minerals. Most clay minerals are structured in sheets of alumina-octahedron and silica-tetrahedron lattices.In terms of shale mineral compositions, the higher percentage of brittle minerals and the lower content of clay minerals can lead to the larger shale brittleness and greater fracturing availability. As for the mechanics properties of rocks, the commonly used characterization parameters include Young’s modulus and Poisson’s ratio.Clay, soil particles the diameters of which are less than 0.005 millimeter; also a rock that is composed essentially of clay particles. Rock in this sense includes soils, ceramic clays, clay shales, mudstones, glacial clays, and deep-sea clays. Clay materials are plastic when wet and coherent when dry.What is Shale. Shale is a type of clastic sedimentary rock that contains mud, flakes of clay minerals and a trace amount of other minerals. More precisely, shale is a thin layer of mudstone. Mudstones have several parallel layers of material. Shale primarily contains mud and clay. But there can be trace amounts of quartz, and calcite.Shale consists of at least 30 percent clay, with varying amounts of quartz, feldspar, carbonates, iron oxides, and organic matter. Oil shale or bituminous also contains kerogen, a mixture of hydrocarbons from deceased plants and animals. Shale is classified based on its mineral content.Failures may occur (1) within shale rock slopes with sliding along specific laminations (highway cuts/open pit benches), (2) by distinct sliding along clay shale beds at varying depths, e.g. Cretaceous clay shales in incised river valleys, (3) along thin discrete folded/tectonised weak shale/clay shale layers in high mountain rock slopes.
