Title: The Influence of Multiple Scales in Fractured Media on Flow and Transport Properties  Abstract: In low-permeability fractured media, such as granites and shales, flow and the associated transport of dissolved solutes is controlled primarily by fractures embedded within the rock matrix. The geometry of individual fractures, size and aperture, as well as the network structure determine the structure of the fluid flow field. However, the relevant lengths scales within a fracture network range several orders of magnitude and it is unclear which features of the network influence which flow and transport properties. One tool to investigate the interplay and influence of these multiple scales are discrete fracture network (DFN) models. In this talk, I’ll discuss recent studies that use high-fidelity DFN models that attempt to link flow and transport attributes to physical structures of a fracture network ranging in-fracture aperture variability to network-scale connectivity.  Bio: Dr. Jeffrey Hyman is a staff scientist in the Earth and Environmental Sciences Division at Los Alamos National Laboratory. He received his PhD in Applied Mathematics from the University of Arizona in 2014 with a PhD Minor in Hydrology and Water Resources. His research focuses on integrating applied mathematics with the geosciences to advance our understanding of coupled subsurface processes in fractured media. He is an Affiliate Faculty in the department of Geology and Geological Engineering at Colorado School of Mines and the director of the Advanced Computational Geosciences Initiative (ACGI) at Los Alamos National Laboratory. He has published over 100 peer-reviewed articles. Dr. Hyman is the principal developer of dfnWorks (2017 R&D 100 Winner) a leading modeling suite for three-dimensional discrete fracture network simulations.
