Upscaling for Improved Oil Recovery

C05 UPSCALING FOR IMPROVED OIL RECOVERY Abstract 1 Upscaling for the simulation of IOR processes is a big challenge for several reasons. Firstly the geological model may be complex in order to resolve important structures such as channels or shales and to target remaining oil. Secondly the recovery processes also tend to be complex involving two-phase or three-phase flow. Careful flow simulation is therefore required to estimate oil recovery. Many upscaling methods have been developed to reduce the number of cells in a geological model so that the models can be used for flow simulation. Inevitably coarse-scale simulations are less
