Examples of 8 × 8 matrix-shaped blocks designed for oil flow in the pores of the formation. The oil-filled sites are shown in color. In these models, quartz has been considered as the formation material and the matrix blocks from left to right belong to the oil concentrations (weight fraction) of 5, 10, and 20%, respectively.
