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 formation volume factor
