The aim of the present work is to implement in COMSOL Multiphysics a multiphase fluid flow model in porous media, also known in the oil reservoir engineering literature as a black oil model, using a standard finite element approach. In particular, we are interested to apply this model coupled with a multiphase, multicomponent transport model to study Enhanced Oil Recovery processes at laboratory scale.

The numerical implementation is validated comparing the results with the analytical solution from the Buckley-Leverett theory, and was showed to reproduce the flow behavior in a water flooding experiment through a sandstone core under laboratory conditions.
