Multilayered reservoirs have been studied in the literature for two types of systems: (1) layers that are separated by impermeable barriers (no formation crossflow) and (2) layers that communicate in the reservoir. In this work, the general problem of distinct n homogenous layers, in which any two adjacent layers are crossflowing in the formation, is solved analytically. A new solution of the corresponding pressure transient behavior is proposed for a uniform-flux vertical well in a multilayered reservoir with formation crossflow. Layer parameters, including permeability, porosity, and layer thickness between crossflowing layers, are distinct for each layer. The solutions are presented for an infinite-acting system with no wellbore storage or skin factor effects.
