This research is aimed at developing a methodology for predicting the performance of unstable displacements in heterogeneous reservoirs. A performance prediction approach that combines numerical modeling with laboratory imaging experiments is being developed. Flow visualization experiments are being performed on laboratory corefloods using X-ray computed tomography (CT) and other imaging technologies to map the insitu fluid saturations in time and space. A systematic procedure is being developed to replicate the experimental image data with high-resolution numerical models of the displacements. The wall-tuned numerical models will then be used to scale the results of the laboratory coreflood experiments to heterogeneous reservoirs in order to predict the performance of unstable displacements in such reservoirs. Accomplishments for the year are presented for the following tasks: flow visualization experiments with CT scanner; flow visualization experiments with imaging workstation; model development and testing; and history match of the flow visualization experiments
