A microscale simulation methodology for subsurface heterogeneity quantification using petrographic image analysis with multiscale mixed finite element method

A microscale heterogeneity quantification methodology is presented, which uses petrographic image analysis with multiscale simulation. Petrographic images of micro-porous carbonate rocks are converted into microscale models with help of an image analysis workflow, which helps in assigning specific porosity, permeability and petro-physical properties to the microscale model. Thin section images are discretized into classes of specific porosity....
