Water formation volume factor
The water formation volume factor represents the change in volume of the brine as it is transported from the reservoir conditions to surface conditions[1].
The units are reservoir barrels per surface barrel at standard conditions, res bbl/STB.
Math and Physics
where
Application range
The correlation is valid through the full range of solids concentrations, temperatures to 260F, and pressures to 5000psia[2].
Example. Calculating water salinity from density
Example source [1]
Input data
= 65.4 lbm/ft3
Calculate water salinity in weight percent solids?
Solution
Nomenclature
= water salinity / solids concentration, ppm
= water salinity / solids concentration, mg/l
= weight percent solids, %
= water specific gravity, dimensionless
