WebJan 30, 2015 · Permeability is the property of a porous material that determines how easily fluid flows through that material—a basic measure of the producibility and injectivity of subsurface formations. Without sufficient formation permeability, oil and gas production, secondary and tertiary recovery, and carbon sequestration are impossible. WebFor uniform and graded structures with the same porosity, their permeability values are different. This is because the internal structure can change the distribution of fluid velocity, which then affects the permeability. It was found that the permeability of graded diamond lattices was slightly lower than that of uniform diamond lattices by 9. ...
