The injection of foams into porous media has gained importance as a method of controlling gas mobility. The multilayer structure of the porous medium raises a question on its efficiency in dealing with layers of different permeabilities. The present work shows the existence of a single traveling wavefront in a two-layer porous medium for a simplifi...

Neglecting or simplifying capillary pressure is a common starting point for analyzing the fluid displacement in porous media. From the mathematical perspective, the effect of such simplifications was addressed in the context of conservation laws. In this paper, we address the issue in the context of traveling waves. Mainly, we are interested in the...

Foam injection is one of the methods that are studied for oil recovery in pre-salt reservoirs. The technique consists in injecting water, gas and surfactant into the reservoir to generate foam. Foam injection allows decreasing the gas mobility, reducing fingering and improving recovery efficiency. In previous work it was proposed a first-order-ki...
