Gas EOR Project 11: Optimal Resolution for Reservoir Characterization in Gas Flooding

Primary Investiagor: Sanjay Srinivasan

In gas flooding processes, many of the mechanisms such as miscibility, dispersion and capillary trapping are controlled by fluid interfaces within pore spaces and accurate characterization of connectivity at that scale is essential for proper upscaling of mechanisms. Ultimately the modeling of these processes and predictions of recovery efficiency have to be made at the pilot or field scale. This implies that heterogeneity at a simuilation grid block scale has to be represented such that it is consistent with the pore level descriptions and finally grid block properties have to reflect the spatial variability at the field scale prescribed by the geological description for the reservoir. The seamless modeling of reservoir heterogeneity across this cascade of scales will be the focus of the proposed research.
