Upscaling Strategies of Porosity-Permeability Correlations in Reacting Environments from Pore-Scale Simulations

Pore-scale Simulations of Pore Clogging and Upscaling with Large Velocities

Computational modelling of processes at pore-scale allows to get detailed insight into their nature. It also provides tools to improve coarse-scale models in which porous medium is considered as a permeable continuum. In this paper, we use the simulations at microscale combined with an upscaling procedure and describe the impact of small changes in the pore morphology on the macroscale paramete...

Dynamic Upscaling from the Pore to the Reservoir Scale

We propose a dynamic three-stage upscaling methodology from the pore scale to the reservoir scale. In traditional upscaling approaches, simulations at smaller scales are used to compute effective transport properties that are used as look-up values in a larger scale simulation. In the proposed approach, simulations at different scales are performed simultaneously. Effective properties are found...

Upscaling of Hydraulic Properties of Fractured Porous Media: Full Permeability Tensor and Continuum Scale Simulations

The simulation of flow and transport phenomena in fractured media is a challenging problem. Despite existing advances in computer capabilities, the fact that fractures can occur over a wide range of scales within porous media compromises the development of detailed flow simulations. Current discrete approaches are limited to systems that contain a small number of fractures. Alternatively, conti...

Global Upscaling of Permeability

Traditional upscaling methods depend on local boundary conditions. It is well known that this approach may introduce large errors in the coarse model. The new method is applicable whenever these local methods fail to produce an acceptable permeability field, e.g. upscaling of blocks close to wells and cases involving heterogeneities on the coarse grid block scale. In such cases, it is impossibl...
