Role of Rock Mechanics in Mining Industry : Applications

Dec 19, 2018  Porosity generally decreases with the age of rocks. It decreases with depth also. Because at greater depth, the rock is subjected to a higher pressure which reduces the pore spaces of the rock mass. Sedimentary rocks have maximum porosity value and the value ranges from 1% to 90%. The igneous rocks have porosity less than 1% to 2%.

Porosity - an overview ScienceDirect Topics

Porosity of reservoir rock is defined as the pore fraction of the rock—that is, the ratio of pore space volume to bulk volume of the rock. Porosity is usually expressed as a percentage: (3.1) Fluid-productive sandstones display porosities ranging between 0.05 to 0.4, or 5% to 40%.
