Numerical simulations of the equation of transport were performed using an adsorption isotherm equation, and a simple cubic polynomial.

The 1D COMSOL implementation included solutes being injected from one face of a homogeneous, isotropic core (small sample of reservoir rock); where the concentration of injected surfactant was kept constant during the simulation.

The spatial distribution of solute adsorption along the rock core was investigated. We attempted to understand the numerical effects of varying several parameters of the transport equations.
