Study of Conceptual Model Uncertainty in Large-Scale CO2 Storage Simulation, A
In this study, multiscale permeability upscaling is combined with a sensitivity study of model boundary condition to identify an optimal heterogeneity resolution in developing a reservoir model to represent a deep saline aquifer in CO2 storage simulation. A three-dimensional, fully heterogeneous reservoir model is built for a deep saline aquifer in western Wyoming, where each grid cell is identified by multiple material tags. On the basis of these tags, permeability upscaling is conducted to create three increasingly simpler site models, a facies model, a layered model, and a formation model. ...
