Permeability is a property of porous materials that is an indication of the ability for fluids (gas or liquid) to flow through them. Fluids can more easily flow through a material with high permeability than one with low permeability. The permeability of a medium is related to the porosity, but also to the shapes of the … See more Permeability in fluid mechanics and the Earth sciences (commonly symbolized as k) is a measure of the ability of a porous material (often, a rock or an unconsolidated material) to allow fluids to pass through it. See more The concept of permeability is of importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs, and of groundwater in aquifers. For a rock to be considered as an exploitable hydrocarbon reservoir without stimulation, its … See more Permeability is typically determined in the lab by application of Darcy's law under steady state conditions or, more generally, by application of various solutions to the diffusion equation for unsteady flow conditions. Permeability needs … See more Sometimes permeability to gases can be somewhat different than those for liquids in the same media. One difference is attributable to … See more The SI unit for permeability is m . A practical unit for permeability is the Darcy (d), or more commonly the millidarcy (md) (1 Darcy $${\displaystyle \approx }$$ 10 m ). The name honors the French Engineer Henry Darcy who first described the flow of water through sand … See more Permeability is part of the proportionality constant in Darcy's law which relates discharge (flow rate) and fluid physical properties (e.g. viscosity), to a pressure gradient applied to the porous media: $${\displaystyle v={\frac {k}{\eta }}{\frac {\Delta P}{\Delta x}}}$$ (for … See more Absolute permeability denotes the permeability in a porous medium that is 100% saturated with a single-phase fluid.
