Research to improve the understanding of how rock fractures form and propagate is essential for the safe and effective development of subsurface energy systems such as geothermal, hydrogen, and carbon sequestration. Integrating research ranging from small-scale laboratory experiments to field-scale testbeds has provided an improved understanding of fracture development over time, but given Earth’s wide-ranging geology, hydrology, geochemistry, and thermal gradients, diverse studies targeted through an energy lens are required to understand fracture behavior in variable geologic settings. We solicit abstracts on research aimed at better understanding fracture formation and propagation in Earth’s geologic settings. Cross-disciplinary research is encouraged, including, but not limited to, research in: 1) multiscale fracture prediction, 2) coupled (thermal-hydro-mechanical-chemical) processes, 3) emerging sensing and data-driven methods, 4) in situ monitoring, 5) machine learning, 6) high-resolution numerical modeling, and 7) innovations in experimental rock physics, which help to forecast and describe fracture formation in subsurface energy systems.
