AbstractIt is vital to retain the 3D geological model main structure and heterogeneity features in the simulation model. This could be assured only through careful design of the simulation model areal grids; representative reservoir simulation layering system and quality controlled petrophysical data up-scaling process. This paper presents the methodology and the QC tools followed to upscale a 25 million cell geological model into a 0.72 million-cell dynamic simulation model, while maintaing reservoir structure and heterogeneity features. Upscaling of the model petrophysical data is a very sensitive and crucial process. Different upscaling techniques were applied to insure best practice. QC tools are developed to check the quality of the upscaling process and its adequacy.A successful application of the structural and petrophysical data upscaling is a key to the construction of a quality simulation model, which is successfully initialized and in the process of history matching.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
