In reservoir engineering or CO2 geological storage a proper well modeling is required to simulate ac curately multiphase flow An efficient method must take into account important well parameters such as the singular pressure distribution in the well vicinity and the large difference of scales between the well bore radius and the reservoir dimension Current methods are based on single phase near well analytical solutions and well indexes developed in the papers of Peaceman Despite the assump tions of 2D uniform rectangular grids in homogeneous media Peaceman's approach is widely used in reservoir simulation However this approach cannot be used in order to take accurately into account heterogeneities This is in particular the case for deviated wells and stratified heterogeneities For this reason a specific model is needed This work addresses the 3D numerical simulation of multiphase flow in near well regions
