The single-cell transport problem for two-phase flow with polymer

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1247225

Polymer injection is a widespread strategy in enhanced oil recovery. Polymer increases the water viscosity and creates a more favorable mobility ratio between the injected water and the displaced oil. The computational cost of simulating polymer injection can be significantly reduced if one splits t...

Discretization of Flow Diagnostics on Stratigraphic and Unstructured Grids

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1160629

Flow diagnostics tools yield quantitative information about the flow behaviour of a model, based on controlled numerical flow experiments. We consider a family of flow diagnostic measures that are constructed based on a single pressure solution and can be used to quickly establish flow patterns and ...

Well-posedness of the Single-cell Transport Problem for Two-phase Flow with Polymer

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1160640

A sequential splitting of the pressure and transport equations applied to a compressible two-phase flow with polymer leads to a considerable speed-up of the simulation, see [1]. To avoid excessive limitation on the size of the time step, the transport equations are solved implicitly. By using an ite...

Fast Simulation of Polymer Injection in Heavy-Oil Reservoirs on the Basis of Topological Sorting and Sequential Splitting

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1137577

We present a set of algorithms for sequential solution of flow and transport that can be used for efficient simulation of polymer injection modeled as a compressible two-phase system. Our formulation gives a set of nonlinear transport equations that can be discretized with standard implicit upwind m...
