| 651-4109-00L | Geothermal Energy | 3 credits | 4G | M. O. Saar, P. Bayer, M. Brehme, P. Deb, F. Samrock | |
| Abstract | The course will introduce students to the general principles of Geothermics and is suitable for students who have a basic knowledge of Geoscience or Environmental Science (equivalent of a Bachelor degree). | ||||
| Learning objective | To provide students with a broad understanding of the systems used to exploit geothermal energy in diverse settings. | ||||
| Content | The course will begin with an overview of heat generation and the thermal structure of the Earth. The basic theory describing the flow of heat in the shallow crust will be covered, as will be the methods used to measure it. Petrophysical parameters of relevance to Geothermics, such as thermal conductivity, heat capacity and radiogenic heat productivity, are described together with the laboratory and borehole measurement techniques used to estimate their values. The focus will then shift towards the exploitation of geothermal heat at various depths and temperatures, ranging from electricity and heat production in various types of deep geothermal systems (including high and medium temperature hydrothermal systems, and Engineered Geothermal Systems at depths of 5 km or more), to ground-source heat pumps installed in boreholes at depths of a few tens to hundreds of meters for heating domestic houses. The subjects covered are as follows: Week 1: Introduction. Earth's thermal structure. Conductive heat flow Week 2: Heat flow measurement. Advective heat flow. Petrophysical parameters and their measurement. Week 3: Temperature measurement. Hydrothermal reservoirs & well productivity Week 4: Hydrological characterisation of reservoirs. Drilling. Optimized systems Week 5: Petrothermal or Engineered Geothermal Systems Week 6: Low-enthalpy systems 1 Week 7: Low-enthalpy systems 2. | ||||
| Lecture notes | The script for each class will be available for download from the Ilias website no later than 1 day before the class. | ||||
| 651-4180-03L | Integrated Earth Systems III  Mit oblig. Workshop/Exkursion am Freitag 11.03.2022: vormittags an der ETH, nachmittags ins Nagra Bohrkernlager | 5 credits | 4G + 1U | S. Heuberger, M. Brehme, T. Driesner, A. Gilli | |
| Abstract | The course Integrated Earth Systems III addresses geological resources (georesources) from an integrative perspective. The course covers three interacting focus themes: 1) non-metallic mineral resources (aggregates, cement raw materials, hydrocarbons), 2) geothermal resources (geothermal energy), 3) metallic mineral resources (ores). | ||||
| Learning objective | The students develop an overview of the different usable geological resources on earth. In particular, they will discuss and amplify their understanding of the genesis of these georesources in the context of the interacting petrological, tectonic, geophysical and geochemical processes. The students will be able to classify the resources' economic significance and to judge their responsible utilisation. | ||||
| Content | Der dritte Teil der Vorlesung "Intergrierte Erdsysteme" behandelt geologische Rohstoffe, die Georessourcen. Drei Schwerpunkte werden in dieser Lehrveranstaltung gesetzt: 1. nicht-metallische mineralische Rohstoffe (Steine & Erden, Kohlenwasserstoffe, Industrieminerale, Salze), 2. Geothermie, 3. Metallische Rohstoffe (Erzlagerstätten). Der Teil der nicht-metallischen mineralischen Rohstoffe diskutiert die Entstehung sowie die Prospektion dieser Rohstoffe an ausgewählten Beispielen. Die Studierenden erhalten Einblick in die tektonischen und sedimentären Bedingungen, die zur Lagerstättenbildung geführt haben, sowie in die zu deren Auffindung benötigten Prospektionstechniken und Geodaten (z.B. 3D-Modelle, Bohrungen, Seismik). Der Geothermie-Teil befasst sich mit der Nutzung von Niedrig- und Hoch-Enthalpie Geothermie-Systemen zur Gewinnung von Wärme und/oder Strom. Die Studierenden werden vom geologischen Untergrund, und den darin vorkommenden und zirkulierenden Flüssigkeiten, über das geothermische Kraftwerk an der Erdoberfläche bis hin zu den Wärme- und/oder Strom-Gestehungskosten, die wesentlichen Aspekte eines geothermischen Kraftwerkes qualitativ und semi-quantitativ untersuchen und beurteilen. Der Teil über Erzlagerstätten stellt ausgewählte Lagerstättentypen und deren Bildung in den Kontext von tektonischen, petrologischen und geochemischen Prozessen. Die Studierenden werden anhand von umfangreichem Probenmaterial die wichtigsten Charakteristika dieser Lagerstätten erarbeiten und die Interpretation von kleinskaligen Feldbeziehungen üben. Daraus werden qualitative und semi-quantitative Rückschlüsse über die chemischen Prozesse hinter der Anreicherung von Erzmetallen abgeleitet. | ||||
| 669-0100-00L | Spring Course: Characterisation of Groundwater Systems Only for CAS in Angewandten Erdwissenschaften. | 2 credits | 2G | M. O. Saar, M. Brehme, M. Willmann | |
| Abstract | The course provides up-to-date hydrogeological knowledge on the description of groundwater systems in hard rocks and sediments. Starting with methods for the characterization of groundwater systems, various case studies are shown, where the application in groundwater protection is highlighted. | ||||
| Learning objective | Participants learn to assess different methods for characterizing aquifers and to link the results of measurements and observations to build a model of the groundwater system. | ||||
| 669-0101-00L | Project Module: Geo-Resources Only for CAS in Angewandten Erdwissenschaften. | 2 credits | 1S | M. Brehme, M. O. Saar, H. Willenberg | |
| Abstract | The project module of the module group Geo-Resources includes a one-day workshop or excursion and the preparation of a joint cooperative online course script by the participants. | ||||
| Learning objective | The participants deepen course content and relate selected topics to their professional practice. | ||||
