MR44A:
Fractures and Fracturing in Chemically Reactive Environment II


Session ID#: 8281

Session Description:
Chemical-mechanical interactions influencing fracture initiation, growth, and coalescence pose a first order control on the time and deformation rate dependent failure of rocks and the development of fracture networks. For example, in the subsurface subcritical fracture growth may lead to time-dependent or progressive failure. Mechanical effects occur almost simultaneously with deformation, while chemical effects occur over longer time scales. Understanding these coupled effects and what controls their spatial and temporal impacts will lead to new insights on the evolution of fractures over all time scales. These processes are relevant to natural and engineered systems, such as fault zone development, advanced recovery of hydrocarbons, storage of CO2 and waste fluids, ore forming processes, and managing geothermal reservoirs.

This session is for research focused on coupled chemical-mechanical processes influencing fracture mechanics, fracture properties, and fluid flow in fractured media. We welcome results from numerical simulation, experimental studies, and field based projects.
