Porosity is the void space between the grains, and thus represents the rock’s capacity to contain fluids (liquid or gaseous hydrocarbons). A highly porous reservoir rock therefore can contain a large volume of oil or gas. But porosity alone will not suffice: the fluids must be able to flow, meaning that the pores must be interconnected. This characteristic, called permeability, is the measurement of the rock’s ability to permit the flow the oil or gas.
