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 … Zobraziť viac The SI unit for permeability is m2. A practical unit for permeability is the Darcy (d), or more commonly the millidarcy (md) (1 Darcy ≈ {\displaystyle \approx } 10−12 m2). The name … Zobraziť viac 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 … Zobraziť viac 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 … Zobraziť viac 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 … Zobraziť viac WebAs shown on Figure 14.1.2 there is a wide range of permeability in geological materials from 10 −12 metres per second (0.000000000001 metres per second) to around 1 metre per second. Unconsolidated materials are generally more permeable than the corresponding rocks (compare sand with sandstone, for example), and the coarser materials are much ...

WebPermeability is a measure of the ease with which fluids will flow though a porous rock, sediment, or soil . Just as with porosity, the packing, shape, and sorting of granular materials control their permeability. Although a rock may be highly porous, if the voids are not interconnected, then fluids within the closed, isolated pores cannot move.
