Define porosity and permeability
WebPorosity can be generated by the development of fractures, in which case it is called fracture porosity. Effective porosity is the interconnected pore volume in a rock that contributes to fluid flow in a reservoir. It excludes isolated pores. Total porosity is the total void space in the rock whether or not it contributes to fluid flow. Thus ... WebThe meaning of PERMEABILITY is the quality or state of being permeable.

If the material has high permeability then the pore spaces are well connected allowing water to completely flow through. However, if there is low permeability then the pore spaces are isolated …
WebJun 26, 2024 · Soil permeability is the quality of a soil enabling it to transmit air or water through the soil pores. Texture, structure, cracking, and the amount of organic matter influence the permeability. The permeability of the least permeable horizon should be estimated because this becomes the most limiting horizon for water and air movement …
WebPermeability is a property of the porous medium that measures the capacity and ability of the formation to transmit fluids.
