KurzbeschreibungThis course presents advanced topics of single/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 their relevance to applications, e.g., groundwater management, geothermal energy, CO2 storage, waste disposal, and oil/gas production.
LernzielThis course presents the tools for understanding and modeling basic physical and chemical processes in the subsurface. In particular, it will focus on fluid flow, reactive transport, heat transfer, and fluid-rock interactions in a porous and/or fractured medium. The students will learn the underlying governing equations, followed by a demonstration of corresponding analytical or/and numerical solutions.
By the end of the course, the student should be able to:
1. Understand, formulate, and derive the governing equations of fluid flow, heat transfer, and solute transport;
2. Understand and apply the underlying physical and chemical processes to simplify and model practical subsurface problems;
3. Solve simple flow problems affected by fluid density (induced by the solute concentration or temperature);
4. Understand and be able to assess the uncertainties pertaining to the reactive transport processes;
5. Assess simple coupled reactive transport problems.
Inhalt1) Introduction to the fundamental concepts of fluid flow in the subsurface
2) Immiscible fluid flow in porous/fractured media
3) Solute transport and heat transfer in subsurface
4) Density-driven flow
5) Uncertainty estimation
6) Reactive transport
7) Fluid injection and production
8) Fluid-rock interactions (non-mechanical)
(8a) mineral and gas solubility in brines
(8b) mineral dissolution/precipitation affecting rock porosity and permeability

KurzbeschreibungThis course focuses on benefits and limitations of geophysical methods applied to problems of high societal relevance. It is demonstrated, how seismics, ground-penetrating-radar and other electromagnetic methods can be employed in geothermics, the cryosphere, hydrocarbon exploration, natural hazard assessments and radioactive waste disposal problems.
LernzielThis course is set up for both, geophysicists and non-geophysicists. The former will become familiar with applications of geophysical methods, for which they have learned the underlying theory in other courses. Non-geophysicists (i.e., potential users of geophysical technics, such as geologists and geotechnical engineers) will learn, which geophysical method or which combination of geophysical methods can be used to solve a particular in their realm.

The main learning goal for both groups is to understand the benefits and limitations of geophysical techniques for important applications, such as exploration problems, waste disposal, or natural hazards.
InhaltDuring the first part of the course, various themes will be introduced, in which geophysical methods play a key role.

Module 1 (25.2./4.3): Geothermal Energy (M. Saar)

Module 2 (11.3.): Natural Hazards (H.R. Maurer)

Module 3 (18.3.): Cryosphere Applications (H.R. Maurer)

Module 4 (25.3./1.4.): Radioactive Waste Disposal (T. Spillmann)

Module 5 (15.4.): Marine Seismics (J. Robertsson)

Module 6 (22.4.): Hydrocarbon Exploration (Fons ten Kroode)

During the second part of the course, we will focus on Deep Underground Laboratories. They offer exciting opportunities for research associated with many themes covered in Modules 1 to 6. This block starts with an introductory lecture (29.4.), followed by visits of the three main Deep Underground Laboratories in Switzerland:

6.5: Bedretto Laboratory

20.5 .: Mont Terri Laboratory

27.5.: Grimsel Test Site

The laboratory visits will occupy the full afternoons of the respective days. Of course, the visits will only be possible, when the COVID-19 situation will be appropriate. Otherwise, virtual laboratory tours are planned. For earning the credit points, at least two out of the three laboratory visits are mandatory, but the students are encouraged, to join all visits.

Active participation of the students will be required. Prior to the laboratory visits, the students must familiarize themselves with one experiment (in total, not per laboratory), and they will introduce this experiment during the visit to their fellow students. Finally, a short report on the experiment assigned will have to be written. Presentation and report will contribute 50% to the final grade.

The remaining 50% of the final grade will be earned during a project work on June 3. The students will receive a small project out of the themes of Modules 1 to 6. During a few hours, they will work independently on the project, and they have to summarize their results in a short report.
SkriptCourse material will be provided in the teaching repository associated with this course.
