Reservoir modeling is playing an increasingly important role in developing and producing
hydrocarbon reserves. In this paper, we provide a brief overview of some main challenges in …

In this paper, an extension of the multi-scale finite-volume (MSFV) method is devised, which
allows to simulate flow and transport in reservoirs with complex well configurations. The new …

The multiscale nature of geological formations can have a strong impact on subsurface flow
processes. In an attempt to characterize these formations at all relevant length scales, highly …

Flow simulation in a reservoir can be highly impacted by upscaling errors. These errors can
be reduced by using simulation grids with cells as homogeneous as possible, hence …

To remove some of the ambiguities in a heterogeneous oil reservoir, a three dimensional
model of the reservoir would be constructed by application of newly introduced methods …

We present a new global scale-up technology for calculating effective permeability and/or
transmissibility. Using this innovative technology, we apply global flow solutions to improve …

An accurate and efficient reservoir modeling process is essential for developing and
producing hydrocarbon reserves, especially from unconventional resources. In this paper …

Near-well effects can have a strong impact on reservoir flow. Current reservoir modeling
practice often uses coarse-scale flow simulation models, which may lead to biased results …

Tight gas and shale gas reservoirs provide almost half of the current US domestic gas
production, with significant projected increases in the next several decades. These …

Geostatistical models of reservoir properties are high resolution with many grid cells; it is
impractical to use them directly in flow simulation because of computational costs. Upscaling …
