Permeability in geology
WebMay 11, 2024 · What is the definition of permeability in geology? Permeability: a measure of the ability of a material (such as rocks) to transmit fluids. Porosity and permeability are related properties of any rock or loose sediment. Why is permeability importance in petroleum engineering? WebThe permeability of a material is determined by assessing how much a material resists the flow of fluids—if it takes a lot of pressure to squeeze fluid through the material it has low …
