Permeability of clay
WebPermeability refers to how connected pore spaces are to one another. If the material has high permeability than pore spaces are connected to one another allowing water to flow … WebPermeability is related to how easily a thing conducts water flowing downhill. If a solid has large connected voids, then it will be highly permeable. The best water flow occurs through a pipe, which is like a single void in a rock. silt has tiny …

WebFeb 19, 2024 · The permeability of shales is several orders of magnitude lower than that of coarser-grained rocks such as sandstone. Therefore, shales and even sandstones with a moderate amount of clay content (shaly sandstones) control the flow at which fluids move underground. Clay can reduce porosity, increase tortuosity and block the pore throats.
