Water viscosity
The formation water (brine) isothermal viscosity correlation is published by McCain in 1991[1].
Water viscosity [2]
Math and Physics
where
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[1].
Discussion
We, at pengtools.com, are calculating water compressibility below the bubble point with the same equation at the moment.
Example. Calculating water isothermal compressibility
Example source [2]
Input data
Calculate water isothermal compressibility at 3500 psia and 165°F?
Solution
Nomenclature
= pressure correction, res bbl/STB- = water salinity or solids concentration, mg/l
= pressure, psia
= Temperature, °F
