In physisorption, there is a weak Van der Waals attraction between the adsorbate and the solid. In low pressure adsorption experiments the temperature–pressure regime is below the critical point of the fluid used. These experiments yield valuable information about the textural properties of porous material, such as surface area and pore

where c f is the formation (rock) compressibility with common units of psi − 1, V p is pore volume, p is pressure in psi, and the subscript T denotes that the partial derivative is taken at constant temperature. The effective rock compressibility is considered a positive quantity that is additive to fluid compressibility; therefore, pore volume decreases as fluid pressure decreases [26, 66].
