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
$dvwp = -1.95301e-9 * $psi * $F - 1.72834e-13 * pow($psi, 2) * $F - 3.58922e-7 * $psi - 2.25341e-10 * pow($psi, 2); $dvwt = -1.0001e-2 + 1.33391e-4 * $F + 5.50654e-7 * pow($F, 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
