Permeability, or intrinsic permeability, (k, unit: m 2) is a part of this, and is a specific property characteristic of the solid skeleton and the microstructure of the porous medium itself, independently of the nature and properties of the fluid flowing through the pores of the medium. 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 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. See more Absolute permeability denotes the permeability in a porous medium that is 100% saturated with a single-phase fluid. This may also be called the intrinsic permeability or specific permeability. These terms refer to the quality that the permeability value … See more 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 … 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 … See more WebIntrinsic permeability "A measure of the relative ease with which a porous medium can transmit a fluid under a potential gradient and is a property of the medium alone" (Lohman et al 1972).
