Effect of Adsorption, Dispersion and Slug Size on Chemical EOR.

Analytical solutions for the diffusion equation for the case of a finite slug injection are derived considering adsorption and dispersion. It was found that the adsorption constant can be combined with the injected pore volume and the slug volume resulting in a modified definition of these dimension...
