CO2-Flooding

Feasible to prove experimentally

@ laboratory-scale

that residual oil saturation

gets minimized

upon oil getting displaced

by a completely miscible fluid (corresponding to an infinite Capillary Number),

while, a certain amount of oil gets retained behind the flood front

(and this residual oil saturation remains affected by IFT

between oil & displacing fluid),

when the oil gets immiscibly displaced?
