Dr. Rainer H. Helmig is the 2015 Henry Darcy Distinguished Lecture Series in Groundwater Science.Helmig is head of the Department of Hydromechanics and Modelling of Hydrosystems at the Institute for Modelling Hydraulic and Environmental Systems, University of Stuttgart, Germany.
“Evaluating the Competitive Use of the Subsurface: The Influence of Energy Storage and Production in Groundwater.”
In this lecture, Helmig will provide insight into how advanced numerical models may be used to analyze and predict the mutual influence of subsurface projects and their impact on groundwater reservoirs, and the expanding need to do so.
For example, as the subsurface is increasingly being used both as a resource and as an energy and waste repository, resource conflicts are becoming more common and complex, such as thermal energy storage and the effects surrounding hydraulic fracturing in both geothermal and shale gas production.
During this lecture, participants will learn about:
- Possible utilization conflicts in subsurface systems and how the groundwater is affected
- Fundamental properties and functions of a compositional multiphase system in a porous medium; basic multiscale and multiphysics concepts will be introduced and conservation laws formulated
- Large-scale simulation that shows the general applicability of the modeling concepts of such complicated natural systems, especially the impact on the groundwater of simultaneously using geothermal energy and storing chemical and thermal energy, and how such real large-scale systems provide a good environment for balancing the efficiency potential and possible weaknesses of the approaches discussed.
Rainer H. Helmig, Ph.D., is head of the Department of Hydromechanics and Modelling of Hydrosystems at the Institute for Modelling Hydraulic and Environmental Systems, University of Stuttgart, Germany. His research covers fundamental research and applied science in the field of porous-media flow. A major focus is on developing methods for coupling hydrosystem compartments and complex flow and transport processes. This is based on simulation methods and techniques for describing single- and multiphase, multicomponent flow and transport processes in the subsurface, i.e., in porous and fractured-porous media.
