Permeability in oil and gas
WebChapter 3: Porosity and Permeability OVERVIEW The nature of reservoir rocks containing oil and gas dictates the quantities of fluids trapped within the void space of these rocks, the ability of these fluids to flow through the rocks, and other related physical properties. WebPermeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence …
