WebPore space in rock contains oil, gas, or water; evaluating fluid saturations is an integral part of analyzing reservoir quality. In tight gas sandstone reservoirs, water saturation is often negatively correlated to porosity (Ma et al., 2011 ). In shale gas reservoirs, gas-in-place includes adsorbed and free gas. WebShale is most often dark gray or black but can be almost any color including red, green, and brown. It is very fine-grained, made of particles invisible to the naked eye. It has a …

Use the answer key to check students' answers … Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers … See more Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding planes. … See more Shales are typically gray in color and are composed of clay minerals and quartz grains.
