Gas/Oil Interfacial Tension correlation in the PVT software at pengtools.com

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

\rho_{wSC} = C_{mg/l}/25000 + 62.428[1]

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
