Resumo: Web-link for the seminar will appear at the day of the lecture in http://fluid.impa.br

We present the wave structure of the Riemann problem for a system of three conservation laws for a three-phase flow in a porous medium taking into account the effects of changes in the aqueous phase due to a polymer injection. The solution consists of slow, transitional and fast saturation waves concatenated with polymer concentration contact waves.
