The density of formation water (brine) at standard conditions (14.7psia & 60°F):

 \rho_{wSC} = C_{mg/l}/25000 + 62.428

The density of formation water (brine) at reservoir conditions:

 \rho_{wR}=\rho_{wSC}/B_w [1]

Nomenclature

 B_w = water formation volume factor, res bbl/STB
 C_{mg/l} = water salinity or solids concentration, mg/l
 \rho_{wSC} = water density at standard conditions, lbm/ft3
