WebSep 10, 2014 · Porosity • Porosity is a measure of the void space in rock, hence, measures how much HC in rock • Porosity φ = Vp/Vb = (Vb-Vm)/Vb; Vb = Vp + Vm – theoretically, φ varies from 0% - 47.6% – In practice, φ varies between 3% and 37% • Porosity is a function of particle size distribution: – Framework materials (sandstone) – high φ ... WebNov 2, 2024 · Porosity is the open spaces between grains or trapped in grains in a microstructure — the presence of tiny openings or spaces within a material. Porous materials can absorb fluids or moisture, which causes corrosion. Porosity is a fraction between 0 and 1, typically ranging from less than 0.01 for solid granite to more than 0.5 …
