Difference between porosity and permeability
WebDec 22, 2024 · A measure of permeability is the degree to which the spaces are connected. Low permeability is usually the result of low porosity. It’s possible to have a rock with … WebPorosity is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock. Permeability is a measure of the ease with which a fluid (water in this case) can move through a porous rock. The pore space, or porosity, of a rock or sediment is the amount of the material that is open space.
