Lateral fluid flow in layered reservoirs is influenced by local crossflow between layers. This paper considers single-phase flow of a slightly compressible fluid in a system of n homogeneous layers, separated by thin, semipermeable shales with negligible storage. The model considers all layers open to a single well, which flows at constant total rate. Numerical solutions of the model equations are used to find the structure of crossflow in typical cases. Analytical solutions for pressure and the n-1 crossflows are developed and compared with the numerical results. The analytical solutions show how the crossflows depend on layer properties and ordering.
