A general 3D flow and transport model in porous media was derived applying an
axiomatic continuum modeling approach, which was implemented using the finite element method
to numerically simulate, analyze and interpret microbial enhanced oil recovery (MEOR) processes
under laboratory conditions at core scale. From the methodological point of view the development
stages (conceptual, mathematical, numerical and computational) of the model are shown. This
model can be used as a research tool to investigate the effect on the flow behavior, and consequently
the impact on the oil recovery, due to clogging/declogging phenomena by biomass production, and
interfacial tension changes because of biosurfactant production. The model was validated and then
applied to a case study. The experimental results were accurately predicted by the simulations.
Due to its generality, the model can be easily extended and applied to other cases.
