Production well
Injection well
(Steam is injected) Injected steam creates a
chamber which heats the
oil.
Oil moves down towards the
production well under the
influence of gravity.

flow of these oils, at ambient temperatures is that of a Bingham plastic fluid which
indicates that the semi-solid structure needs high shear to be broken down which
can initiate flow in these oils (Ghaffari et al. 2017). Figure 4 shows the contrasting
