Put forward problem: Sand grains and particles of carbonate materials that make up sandstone and limestone reservoirs usually never fit together perfectly due to the high degree of irregularity in shape.The void space created throughout the beds between grains,called pore space or interstice,is occupied by fluids (liquids and/or gases)
