Additive crystalline salt and water amount to increase the density - Method I (two-salt systems)
Input(s)
\(V_{i}\): Volume of Initial Brine (bbl)
\(V_{w}\): Total Water Volume to add to achieve the Final Brine Density (bbl)
\(C_{m s f}\): Concentration of More Soluble Salt in Final Brine Formulation (%) \((\mathrm{lbm} / \mathrm{bbl})\)
\(C_{l s f}\): Concentration of Less Soluble Salt in Final Brine Formulation \((\mathrm{lbm} / \mathrm{bbl})\)
\(C_{m s i}\): Concentration of More Soluble Salt in Initial Brine Formulation (lbm/bbl)
\(C_{l s i}\): Concentration of Less Soluble Salt in Initial Brine Formulation (lbm/bbl)
\(W_{i}\): Water Fraction in Initial Brine Formulation (fraction)
\(W_{f}\): Water Fraction in Final Brine Formulation (fraction)
\(V_{f}\): Final Volume of Brine after Adjustment (bbl)
Output(s)
\(m_{m s}\): Additional More Soluble Salt need to raise the Brine Density (lbm)
