A variety of approaches for gridding and upscaling of detailed geocellular models for flow
simulation are reviewed. Local, extended local, global and quasi global techniques for the …

A new technique for upscaling highly variable permeability descriptions is developed and
demonstrated. The method provides coarse scale numerical properties (transmissibilities) …

We review and perform comparison studies for three recent multiscale methods for solving
elliptic problems in porous media flow; the multiscale mixed finite-element method, the …

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 …

A methodology for transport upscaling of three-dimensional highly heterogeneous
formations is developed and demonstrated. The overall approach requires a prior hydraulic …

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 …

Carbonate reservoirs are extremely challenging for reservoir modeling and flow simulation
due to their high heterogeneity and the complexity of controls on the porosity and …

A hybrid, multiscale reservoir simulator has been developed that directly substitutes pore-
scale models for continuum-scale, finite-difference grids. Over 7500 pore scale models (∼ …

Currently, to build models for dynamic simulations of large oil and gas fields, engineers have
to upscale the original geological grid not to exceed limits set but by computer memory size …
