Mission Statement

The Geothermal Energy & Geofluids group is endowed by the Werner Siemens Foundation and investigates reactive fluid (water, CO2, CxHy, N2) and (geothermal) energy (heat, pressure) transfer in the Earth’s crust employing computer simulations, laboratory experiments and field analyses to gain fundamental insights and to address a wide range of societal goals and concerns.

Open Positions

Lectures & Courses

Geofluids

X.‑Z. Kong, A. Ebigbo, 651-4240-00L
This course presents advanced topics of single and multiphase fluid flow, heat transfer, reactive transport, and geochemical reactions in the subsurface. Emphasis is on the understanding of the underlying governing equations of each physical and chemical process, and its relevance to applications, e.g., groundwater management, geothermal energy, CO2 storage, waste disposal, and oil/gas production.
