Abstract
Complex coupled processes occur in natural geothermal systems and result from injection and production of fluid in geothermal reservoirs. Fluid flow and heat transfer interact with rock mechanical deformations and shear-dilation, opening and propagation of fractures. Extension of fractures and changes in fracture aperture is again strongly coupled to flow and transport. This process-structure interaction occurs both related to natural convection processes in deep geothermal systems and during the development and operational phase of a reservoir when fluids are injected and produced. The coupled processes and their interaction with the fractured structure of the formation has a strong impact on the heat transfer in deep geothermal systems as well as on the outcome of fluid injection and production operations. In this talk, we discuss mathematical models and numerical approaches for coupled processes and process-structure interaction in geothermal reservoirs. Modeling examples will be discussed considering both natural and engineered systems.
