Porosity and Permeability - Louisiana Department of ...
Porosity and Permeability Porosity: is a measure of the void spaces in a material Permeability: a measure of the ability of a material (such as rocks) to transmit fluids Porosity and permeability are related properties of any rock or loose sediment. Both are related to the number, size, and connections of openings in the rock.

www.ees.nmt.eduRelationship to Porosity ¥Note that k typically cannot be correlated with porosity. ¥For example, clay has a very high porosity but very low permeability, Ðwhile well-sorted gravel, which also has high porosity, has a high permeability ¥However, within a single lithologic type (such as sandstone), k typically increases with increasing ...

Shrinkage porosity appears during material solidification phase, which begins with mold filling phase and ends when every part of the material is completely solidified. The cause of its creation is material shrink and, for this reason, porosity is as

wwwrcamnl.wr.usgs.govPorosity is often conceptually partitioned into two components, most commonly called textural and structural porosity. The textural component is the value the porosity would have if the arrangement of the particles were random, as described above for granular mate-rial without cementing. That is, the textural
