WebSep 29, 2014 · Permeability is a measure of the ability of a fluid to pass through its porous medium. Permeability is one of important to determine the effective reservoir. Porosity and permeability are two properties describing the reservoir rock capacity with regard to the fluid continence. Moreover, a reservoir rock can be porous without being permeable. WebPorosity and Permeability Porosity: is a measure of the void spaces in a material 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. Both are related to the number, size, and connections of openings in the rock.
