| 651-4106-03L | Geophysical Field Work and Processing: Preparation and Field Work | O | 7 credits | 3V + 11P | C. Schmelzbach, P. Nagy, A. Wieser | |
| Abstract | The 'Preparation' and 'Field Work' parts of 'Geophysical Field Work and Processing' involve the planing and conducting of a near-surface geophysical field campaign using common geophysical techniques to study, for example, archeological remains, internal structures of landslides or aquifers. Students work in small groups, and plan, acquire, process and document a field campaign together. | |||||
| Objective | Students should acquire the knowledge to (1) design and plan a geophysical survey appropriate for the target of investigation, (2) acquire geophysical data, (3) process the data using state-of-the-art techniques and software, (3) analyze and interpret the results, and (4) write a report according to commercial and scientific standards. | |||||
| Content | The course is split into two parts: 1. 'Preparation': Introductory lectures and exercises (lab and field) covering Geographical Information Systems (GIS), surveying, and introductions to the field sites. Participation in the 'Preparation' part is a REQUIREMENT to participate in the 'Field Work' part. 2. 'Field Work': Four-weeks field course. The students work in groups on the following topics: - Planning and design of a comprehensive geophysical survey - Data acquisition - Data processing and inversion - Interpretation of the results - Report writing | |||||
| Lecture notes | Relevant reading material, manuals and instructions for all methods of the field course will be handed out to each group at the beginning of the 'Field Work' part (beginning of June). | |||||
| Prerequisites / Notice | A "pass" (Swiss grade 4.0 or higher) in the written examination of 651-4104-00 V Geophysical Fieldwork and Processing: Methods, is an absolute REQUIREMENT to participate in this course. Students registering for the course confirm having read and accepted the terms and conditions for excursions and field courses of D-ERDW Link | |||||
| 651-4018-00L | Borehole Geophysics | O | 3 credits | 3G | M. Hertrich, X. Ma | |
| Abstract | This introductory course on borehole geophysical methods covers the application of borehole logging and borehole-borehole and borehole-surface seismic, and radar imaging to rock mass and reservoir characterization. The principles of operation of various logging sondes will be covered as well as their application. The emphasis is on geotechnical rather than oil and gas well reservoir engineering. | |||||
| Objective | The course will introduce students to modern borehole logging techniques with the emphasis on geotechnical rather than oil and gas well reservoir engineering. Although the principles of operation of the various sondes will be covered, the primary focus will be on application. For a given problem in a given environment, the students should be able to design a logging program that will furnish the requisite information. They will also be able to extract information on rock mass/reservoir properties by combining curves from a suite of logs. The students will also learn about surface-to-borehole and borehole-to-borehole seismic methods for rock mass characterisation. This will include VSP and tomography. | |||||
| Content | - General introduction to geophysical logging - Discussion of various logging types including - Caliper logs - Televiewer logs - Flowmeter and temperature logs - Resistivity logs - Nuclear logs - Sonic logs - Suface-to-borehole and borehole-to-borehole methods - Instrumentation - Vertical seismic profiling - Crosshole tomography - Applications | |||||
| Lecture notes | A pdf copy of the lecture will be posted on the course website no later than the day before each class. | |||||

| 651-4109-00L | Geothermal Energy | O | 3 credits | 4G | M. O. Saar, P. Bayer, E. Rossi, 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). | |||||
| 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. | |||||
