Dynamic immiscible displacement mechanisms in pore doublets: theory versus experiment
This work discusses the controversy, found in the published literature, over the microscopic displacement mechanism and the displacement efficiency in the pore doublet model. To this end, published notions are critically reviewed and the weaknesses of the assumptions used in deriving various criteria for the motion of the fluid-fluid interfaces are identified. Theoretical considerations of the motion of fluid-fluid interfaces of different curvatures, interacting in pore doublet arrangements, led to the realization of new mechanisms of entrapment of the displaced phase. These new mechanisms, along with the pore structure parameters and the displacement conditions prevailing at the pore level that jointly account for entrapment, were established with the help of appropriate displacement experiments recorded on photographs depicting the advance of fluid-fluid interfaces in transparent pore doublet models.
