Learning outcomes of the learning unit
At the end of the course, the student will have a strong basic skill in geothermy. He will be able to:
- be familiar with the main characteristics of geothermal systems;
- make adequate conceptual choices in the function of the local energy demand and local geological and hydrogeological conditions;
- collect and organize the needed data for a first assessment and then a feasibility study of the geothermal system;
- calculate basic feasibility aspects of a deep as well as of a shallow geothermal system;
- detect advantages and drawbacks in the choice of a site for geothermal use;
- assess/calculate the mid- and long-term behavior of a geothermal system in the function of the underground characteristics;
- assess possible impacts on the groundwater resources of a geothermal system.
This course contributes to the learning outcomes I.1, I.2, I.3, II.1, II.2, III.1, III.2, III.3, IV.1, IV.3, IV.4, IV.5, V.1, V.2, VI.1, VI.2, VI.3, VI.4, VII.1, VII.3, VII.5, VII.6 of the MSc in geological and mining engineering.
Prerequisite knowledge and skills
Basic knowledge and understanding of geology and hydrogeology. Elementary notions of physics (essentially thermodynamics) and chemistry. No official prerequisite course is compulsory.
Planned learning activities and teaching methods
The course is composed of "ex-cathedra" lectures (see content above). Practical work/exercise (30h) consists of a study of the ideal geothermal systems in one given site and for a given specific energy demand (i.e. on the basis of geological, hydrogeological, geomechanical, and thermal basic data, each group of students must prepare concurrent projects).
Mode of delivery (face to face, distance learning, hybrid learning)
Blended learning
Additional information:
Face-to-face for theory teaching.
In groups for practical work.
Recommended or required readings
A pdf copy of slides and different publications will be made available on eCampus. For the shallow geothermy with open systems, it could be useful to check chapter 11 of the following book: Dassargues, A. 2018. Hydrogeology: groundwater science and engineering. Taylor & Francis CRC Press, 472p.
Assessment methods and criteria
Exam(s) in session
Any session
- In-person
oral exam
- Remote
oral exam
Additional information:
The oral exam consists of a short 'professional' ppt presentation of the main results from the practical work, then questions by the professors acting as 'stakeholders' of the geothermal operation ...
The ppt presentation is about the results of the group's practical work. Individual questions will be asked by the professors.
Good knowledge and a perfect command of the fundamentals from all the concerned topics of this geothermy course are indeed needed for being able to provide adequate answers.

Organizational remarks
The course will be given during the 2nd semester. The schedule and the room should be checked on CELCAT.
