... steady-state pressure drop is actually below that of waterflooding steady state pressure drop. This is due to diminished displacement efficiency for later sections of the core which take place during unstable waterflood displacement which results in reduced relative permeability to water. As is discussed...

By contrast, positive temperature gradients lead to more compact displacement fronts, hence better recovery efficiencies. In addition, in the latter case, temperature is higher than...
