Input(s)

$f_{h}$: Mole Fraction of Hydrocarbon Gas (dimensionless)

$f_{\mathrm{CO}_{2}}$: Mole Fraction of Carbon Dioxide (dimensionless)

$f_{\mathrm{H}_{2}} \mathrm{~S}$: Mole Fraction of Hydrogen Sulphure (dimensionless)

$r_{s h}$: Solubility of Hydrocarbon Gas (SCF/bbl)

$r_{\mathrm{SCO}_{2}}$: Solubility of Carbon Dioxide $(\mathrm{SCF} / \mathrm{bbl})$

$r_{\mathrm{sH}_{2} \mathrm{~S}} \mathrm{~S}$ Solubility of Hydrogen Sulphure $(\mathrm{SCF} / \mathrm{bbl})$

Output(s)

$d r_{s(o, w, e)}$: Combined Solubility of Hydrocarbon Gas, $\mathrm{CO}_{2}$ and $\mathrm{H}_{2} \mathrm{~S}(\mathrm{SCF} / \mathrm{bbl})$
