A major challenge for Previous HitreservoirNext Hit transport modeling is to obtain Previous HitreservoirNext Hit transport parameters at field scale for accurately Previous HitpredictingNext Hit the influences of physical and chemical heterogeneity on oil/gas/solute transport. This study is to develop a new method for upscaling Previous HitreservoirNext Hit transport parameters for fractured porous media with multimodal matrix. First establishes a concept model of Previous HitreservoirNext Hit reactive mineral facies with three hierarchical structures including reactive minerals, reactive mineral assemblages and reactive mineral facies; second using mass transfer coefficient in dual Previous HitporosityNext Hit model for fractured porous media, the upscaling equations will be derived for hierarchical multimodal matrix in combination of indicator geostatistics and hierarchical transition probability model and stochastic method. Then, Monte Carlo simulations will be conducted to verify the proposed upscaling method. Subsequently, the developed upscaling method will be applied to a fractured Previous HitreservoirNext Hit at Rulison site located in the south-central Piceance Basin in west central Colorado, where natural gas (oil) is trapped in fractured Previous HitsandstoneNext Hit lenses interbedded with shale within Williams Fork Formation of Mesaverde Group in Upper Cretaceous. Nuclear stimulation of the low-permeability Previous HitreservoirNext Hit was conducted in 1960s and 1970s. Radionuclide transport and transfer of water and natural gas with tritium in fractured rocks become major concerns because of commercial development of natural gas and environmental protection from radionuclides. Upscaling will bridge the transport parameters gap between the different scales and provide a theoretical and practical link from the laboratory bench to the field scale at which Previous HitreservoirTop transport modeling, risk assessment and contaminant remediation are actually conducted.
