Geomechanics & Geophysics for Energy and the Environment
Duke's Geomechanics and Geophysics for Energy and the Environment (GGEE) research group works to understand and address issues related to underground engineering, exploration, resource use and environmental hazards. Our faculty develop mathematical models to study and predict interactions among the chemical, thermal and mechanical processes in soils and rocks, as well as noninvasive techniques for interrogating and characterizing sub-surface properties.
Applications of our work include exploration and engineering of deep, high pressure/high temperature energy resources such as oil, gas, methane hydrates and hot water or vapor. Unconventional approaches to resource extraction demand integration across science fields, and geomechanics bridges the gap from geology and geophysics to engineering in a way that is only now becoming more widely appreciated in the energy industry. Our research also addresses geo-hazards such as earthquakes, sinkholes, desiccation soil cracking, material degradation, geostructure degradation, landslides and mudslides; geomechanics principles are utilized to assess wellbore stability, reservoir properties, nuclear waste geological disposal, landslide stability and hydraulic stimulations including hydraulic fracking.
