Method of characteristics

Modeling and simulation of surfactant–polymer flooding using a new hybrid method
A novel hybrid numerical method for multiphase multicomponent flows in porous media using a combination of a discontinuous finite element method and a modified method of characteristics-based finite difference method. Real world numerical examples are presented for chemical enhanced oil recovery using surfactant-polymer flooding.
