Black Oil (fluid model)

 A simplified version of Modified Black Oil model without volatile oil  $//<![CDATA[ \begin{array}{l}R_v =0\end{array} //]]>$.

Consist of three chemical components   $//<![CDATA[ \begin{array}{l}C = \{ W, O, G \}\end{array} //]]>$:

$//<![CDATA[ \begin{array}{l}W\end{array} //]]>$ – water substance with minerals  (assuming formation water and injection water composition is the same)

$//<![CDATA[ \begin{array}{l}O\end{array} //]]>$ –  oil liquid component 

$//<![CDATA[ \begin{array}{l}G\end{array} //]]>$ – light alkanes component,

persisting in three possible phases $//<![CDATA[ \begin{array}{l}\alpha = \{ w, o, g \}\end{array} //]]>$:

$//<![CDATA[ \begin{array}{l}w\end{array} //]]>$ – water phase (water-based liquid phase)

$//<![CDATA[ \begin{array}{l}o\end{array} //]]>$ –  oil phase (liquid phase with oil and dissolved gas,

$//<![CDATA[ \begin{array}{l}g\end{array} //]]>$ – gas phase (gas-based gaseous phase).

The accountable cross-phase exchanges are illustrated in the table below:
