A core sample has a diameter of 5 cm and a length of 10 em. The porosity of the core sample is measured to be (1.25. Initially the core sample contains only oil in the pores. A displacement experiment is eondueted where water is injected through the left side of the core and water and oil are produced through the right side. At the end of the experiment, 5 Pole Volumes (PU, where 1 PV is equal to the pore volume of the core sample} of water have been injected into the core and 4.? PV's of water has been produced. Please compute the volume of oil that remains in the core and the Volume ofoil that has been produeed in 1113+
