Abstract
In this paper two different 2D synthetic reservoirs have been used to model tracer transport to better understand the geological structure of the reservoir, by sequentially solving Brinkman’s equation followed by the advection-diffusion-adsorption equation using the cell centred finite volume approach. The use of Brinkman’s equation is motivated by the fact that it simplifies the numerical modelling by allowing the use of a single equation to model the effect of both free flow and porous regions, thus in effect reducing the error due to improper modelling of the interface between the two regions. The same problems were also solved using Darcy’s equation for flow modelling, by using highly contrasting permeability values between the two regimes, this served as the control case used for comparison of the results.
