Water compressibility
The formation water (brine) isothermal compressibility data is published in 1990 by McCain[1].
Water compressibility data [1]
Math and Physics
At pressures above bubble point:
Application range
The correlation is valid only for temperatures between 200 and 270F, pressures of 1000 to 20000 psia, and salinities up to 200000 mg/l[2].
Discussion
We, at pengtools.com, are calculating water compressibility below the bubble point with the same equation at the moment.

Input data
Calculate water isothermal compressibility at 3500 psia and 165°F?
Solution
The solution is also available in the PVT software model at [The solution is available in the PVT calculator software model at www.pengtools.com
