This paper presents the results of applying the Buckley and Leverett displacement theory to petroleum reservoirs consisting of a finite number of layers. It is assumed that the layers communicate only in the well bores and that the reservoir may be represented as a linear system. Most previous investigations of this nature were limited by their assumptions and by inconsistent calculation techniques. This study makes an improvement on the previous work by applying the Buckley-Leverett displacement theory to a noncommunicating layered system where permeability, porosity, initial saturation, residual saturation, and relative permeability vary from layer to layer in a logical and consistent manner. Gravity and capillary-pressure effects are neglected. A modification of the Higgins-Leighton calculation method was used in this study. Waterflood predictions were made with all properties varying and with only permeability varying using several mobility ratios. (21 refs.)
