Conventional and unconventional hydrocarbon rocks have complicated pore structures with
heterogeneities distributed over various length scales (from nanometre to centimetre or even …

The multiscale finite volume (MSFV) method is a computationally efficient numerical method
for the solution of elliptic and parabolic problems with heterogeneous coefficients. It has …

Improving conformance control in reservoirs with a heterogeneous permeability distribution
is the objective of many enhanced oil recovery (EOR) methods. In recent years, the injection …

To apply upscaling techniques is an undeniable demand in reservoir simulation, when one
considers the difference between the level of detail in a geological model and the level of …

In this thesis, the multiscale finite-volume (MSFV) method for the solution of elliptic problems
is extended to an efficient iterative algorithm that converges to the fine-scale numerical …

The generation of reservoir grids has to take into account numerous flow parameters, static
and dynamic, from the fine-scale geological models to minimize discretization errors. These …

The response of gas condensate reservoirs is directly influenced by heterogeneity. In such
reservoirs, condensate is created around wellbore areas, when the reservoir pressure falls …

We present a novel unstructured coarse grid generation technique based on vorticity for
upscaling two-phase flow in permeable media. In the technique, the fineness of the …

Reservoir flow simulation involves subdivision of the physical domain into a number of
gridblocks. This is best accomplished with optimized gridpoint density and a minimized …

A novel technique for upscaling of detailed geological reservoir descriptions is presented.
The technique aims at reducing both numerical dispersion and homogenization error …
