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].
Example. Calculating water formation volume factor
Example source [1]
Input data
Calculate water formation volume factor at 3176 psia and 165°F?
Solution
Nomenclature
= water formation volume factor, res bbl/STB
= pressure, psia
= Temperature, °F
= pressure correction, res bbl/STB
= temperature correction, res bbl/STB
