Permeability of Porous Media Nature
WebJan 20, 2024 · Permeability is a function of the geometry of the pore structure of the porous media. Permeability is controlled in sandstone by grain size, grain orientation, packing arrangement, cementation, clay content, bedding, and grain size distribution and sorting. WebJan 1, 2013 · Pore structure characteristics of low permeability porous media Low or ultra-low permeability reservoirs mainly have small pores and thin pore throats. In such porous media, pores are very small, throats are very thin, and the pore/throat ratio is very high. hals buffalo ranch chips
