FIELD: physics.
SUBSTANCE: disclosed is a method (versions) of determining representative elements of areas and volumes in a porous medium. A representative element of area (REA) is the smallest area that can be modelled to yield consistent results, within acceptable limits of variance of the modelled property. Porosity and permeability are examples of such properties. In 3D, the corresponding term is representative element of volume (REV). A REV is the smallest volume of a porous medium that is representative of the measured parameter.
EFFECT: high accuracy of obtained data.
