Fracture intersections need to be investigated to predict fluid flow for a wide range of geoscience applications with important societal impact. These include the efficacy and sustainability of geothermal systems, contaminant remediation, potential long-term subsurface storage of anthropogenic waste (CO₂, radioactive waste) and subsurface recovery and storage of energy fluids (oil & gas). There are many avenues to understand the processes of subsurface flow and we wish to explore laboratory and field experiments in geochemical alterations, wave propagation, electrical resistivity tomography, geophysics, and numerical modeling. Through these methods we wish to address how evolution of intersections affects flow through the subsurface, how stress fields impact intersections, and how damage or fluid alteration affect intersection topology. Utilizing these multidisciplinary methods for fracture intersections in both space and time elucidates the controlling mechanisms for this inherently 4D problem.
