A theoretical and laboratory study of fluid displacement in stratified sands

The main purpose of this Thesis la to develop a better understanding of the mechanics of fluid displacement in stratified sands. Various methods describing fluid displacement in stratified sands will be discussed and their limitations pointed out. This will be followed by a new derivation of the fluid displacement mechanics. This derivation will be rigorous enough to apply to stratified reservoirs for both miscible and immiscible displacements. [...]
