Exercise $1$

You want to EOR from a reservoir with composition depicted by $O_0$ in the ternary diagram. You have been asked to use a lean injection gas of composition $G_0.$

On the ternary phase diagram,

$($i$)$ indicate all fluid compositions between the injection well and the production well

Exercise $1$ cont'

Exercise $1$ Cont.

This combination of $($gas$,$ oil$)$ will result in a vaporising gas drive:

$($ii$)$ Label compositions $G_0,O_0,G_1,G_2,L_1,$ and $L_2$ on the ternary diagram
