Analytically exact and continuous solutions are developed for the space-time relationships of a linear waterflood in a vertically-stratified reservoir model. The solutions represent simple extensions of the analytical, but discrete, spatial relationships of Dykstra and Parsons to analytically continuous expressions. Explicit solutions for time are presented which permit the coupling of all instantaneous and cumulative performance parameters to a completely rational time basis. The continuous nature of the solutions permits unusual fluid behavior to be observed between successive bed breakthrough points. Although the model assumes piston-like displacement, these novel phenomena do not appear to be artifacts of this limiting assumption. 27 references.
