Web1 Porosity and Permeability Lab. Name: Richa Gomes Date: 30/10/ Porosity and Permeability Lab. The terms porosity and permeability are related. Porosity – the amount of empty ('pore') space in a soil, rock or other Earth material; this empty space is known as pore space. Porosity is how much water a substance can hold within itself. WebApr 28, 2024 · It should be kept in mind that the permeability and porosity of clay-bearing rocks measured with gases can be significantly higher than that measured with water as the pore fluid (e.g., Faulkner & Rutter, 2000). Gas permeability and porosity are unlikely to be representative of subsurface fluid flow in clay-rich fault zones.
