Modelling Conductive Faults With a Multiscale Approach Involving Segregation Concept

Reservoir engineers have underlined the difficulties to get both good physical representation and numerical performance in modelleng conductive faults. The present work proposes a representative and efficient model to simulate multiphase flows in highly faulted fields. Our model uses the gravity segregation concept to represent flows in the fault planes. The segregated model has been coupled to a conventional black-oil reservoir simulator modelling the matrix flows within the fault panels. This paper describes the model with its physical basis. Validations against finely-gridded simulations for multiphase displacements in a fault panel are also presented.
