===Water Compressibility===
Compressibility can be calculated by Osif correlation at pressure above the pressure Pb in water and gas systems.

===Water Viscosity===
Greater reservoir pressure affect the viscosity is getting smaller, the higher the salinity increase water viscosity. The higher temperature causes the viscosity decreases. to determine the viscosity of water McCain correlation can be used.
