Gel placement in porous media: Constant injection rate

In this paper we analyse advective transport of polymers, crosslinkers and gel, taking into account non-equilibrium gelation, gel adsorption and cross linker precipitation. In absence of diffusion/dispersion the resulting mode l consists of hyperbolic transport-reaction equations. These equations are studied in several steps using mainly analytical techniques. For simple cas es, we obtain explicit travelling wave solutions, whereas for more complica ted cases we rely on analytical techniques to analyse the problem qualitati vely. Finally, a numerical solution for the full system of equations is obt ained. The results developed in this study can be used to validate numerica l solutions obtained from commercial simulators.
