Gas solubility in a mud system
Input(s)
\(f_{o}\): Volume Fraction of Base Oil (fraction)
\(f_{w}\): Volume Fraction of Water (fraction)
\(f_{e}\): Volume Fraction of Emulsifier (fraction)
\(r_{s o}\): Solution Gas/Component Ratio of Base Oil (fraction)
\(r_{s w}\): Solution Gas/Component Ratio of Water (fraction)
\(r_{s e}\): Solution Gas/Component Ratio of Emulsifier (fraction)
Output(s)
\(r_{s m}\): Solution Gas/Component of the Mud (fraction)
Formula(s)
\[
r_{s m}=f_{o} r_{s o}+f_{w} r_{s w}+f_{e} r_{s e}
\]
