ABSTRACT

The fluid flow and transport phenomena are simulated through three-dimensional consolidated and unconsolidated digital rock slabs representing the geological rock types of the McMurray formation. Finite element simulations are carried out in order to solve the mixing advection-diffusion problem, and the effluent history is processed to predict the longitudinal dispersion coefficient and evaluate the efficiency of miscible displacement processes in the presence of microheterogeneities. According to the results, consolidated samples with non-uniform cementation show a different dispersion behavior when compared to both unconsolidated and uniformly cemented rocks, suggesting that the cementation pattern remarkably influences the miscible-flood performance.
