Permeability in oil and gas
WebThe porosity and permeability of rocks is important in determining which rocks will make a good reservoir. A rock that is both porous and permeable would make a good reservoir rock as it allows oil and gas to move up through the pores in the rock closer to the surface where it can be extracted. WebPermeation. In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. [1]

Webgas) is compressed by infinite pressure and becomes a near perfect liquid. It is because of this that the klinkenberg permeability is often given the symbol k L. The klinkenberg permeability is very commonly used within the oil industry, and should approximate very well to the permeability of the sample measured with liquid flowing through it.
