A cylindrical core, completely saturated with oil up to immobile water saturation, is immersed in water and the measured volume of oil displaced by imbibition of water is 7.5 c.c. The same core is centrifuged under water and the volume of oil removed by centrifuge is 14.4 c.c. What is the water wettability index for the core?
