Permeability and porosity

WebApr 1, 2024 · The short answer is “No” – porosity and permeability are linked but are not the same. Porosity relates to actual pores (or voids) in the structure of a layer or surface, while permeability relates to the ability of a liquid to absorb into a layer or surface. Porosity is a physical phenomenon while permeability is a chemical phenomenon. WebApr 11, 2024 · Porosity, permeability, and compressibility have been measured at eight effective stresses, and the importance of fracture orientation, opening, density, and intersection on poroelastic parameters of fractured porous media is discussed.
