Saturated Water Isothermal Compressibility Coefficient (Cw,s)
The compressibility (also known as the coefficient of compressibility or isothermal compressibility is a measure of the relative volume change of a fluid or solid as a response to the application of pressure. The compressibility of water is a function of pressure and temperature.
At pressures below bubble point, the brine compressibility is a function of water and gas formation volume factors as well as solution gas/water ratio.
