Title: Analytical upscaling of fracture permeability
It is time-consuming and sometimes technically difficult to find the effective permeability of fracture systems using numerical upscaling. An alternative is to use analytical methods, which are much faster but may have limited applicability. For instance, analytical methods usually assume statistical homogeneity, and may be tailored for networks with very high or very low connectivity. In this presentation, I will give an overview of different alternatives for analytical fracture upscaling, and compare their predictions with numerical simulations. The factors that contribute to the upscaling error are highlighted and related to the underlying assumptions of the different analytical methods.
