AB - <p style="text-align: justify;">A new multiphysics model for two-phase compositional flow is
presented. It is designed to fit the level of model complexity to that of the flow
and transport processes taking place in a given region of the domain. Thus, the
model domain is divided into a subdomain which accounts for two-phase compositional
processes and another in which single-phase transport is described.
A coupling of the simple and complex equations gives rise to an efficient model.
Special interest is placed in the discretization of the two-phase compositional
model in a finite-volume context and an IMPES time scheme with decoupled
pressure and transport equations. For optimal subdomain determination, an
easy-to-handle, adaptive scheme is presented. The practical usability is demonstrated
on a real live problem from carbon dioxide sequestration.</p>
