| 651-4018-00L | Borehole Geophysics | 3 credits | 3G | C. Roques, H. Maurer | |
| 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. | ||||
| Learning 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. | ||||

| 651-4087-00L | Case Studies in Exploration and Environmental Geophysics | 3 credits | 3G | H. Maurer, J. Robertsson, M. Hertrich, M. O. Saar | |
| Abstract | Integrated geophysical investigations; applications of exploration seismic; applications of high-resolution seismic, ground-penetrating radar, magnetic, gravity, electromagnetic, geoelectric and nuclear-magnetic resonance methods; case studies. | ||||
| Learning objective | Provide (i) fundamental knowledge of modern methods employed in exploration, engineering and environmental geophysics, (ii) a sound understanding of integrated multidisciplinary approaches for resolving diverse exploration, engineering and environmental problems, and (iii) familiarity with exploration-, engineering- and environment-relevant case histories (national und international). | ||||
| Content | A broad range of geophysical methods are employed in exploration, engineering and environmental projects worldwide. After short introductions to various applied geophysical methods, strategies for resolving a wide variety of exploration, engineering and environmental problems are introduced. Themes addressed in exploration geophysics include exploration and evaluation of marine hydrocarbon reservoirs. Themes addressed in engineering geophysics include: remote sensing in archeology, detection of metal pipes, plastic pipes and caverns in the subsurface, and characterizing the shallow underground in regions of major construction. Themes addressed in environmental geophysics include: exploration and evaluation of groundwater reserves, and investigations of potentially dangerous waste disposal sites (e.g. outlining the boundaries and content of poorly documented landfills and studies of sites for the future storage of chemical and radioactive refuse). | ||||

| 651-4094-00L | Numerical Modelling for Applied Geophysics | 5 credits | 2G | J. Robertsson, H. Maurer | |
| Abstract | Numerical modelling in environmental and exploration geophysics. The course covers different numerical methods such as finite difference and finite element methods applied to solve PDE’s for instance governing seismic wave propagation and geoelectric problems. Prerequisites include basic knowledge of (i) signal processing and applied mathematics such as Fourier analysis and (ii) Matlab. | ||||
| Learning objective | After this course students should have a good overview of numerical modelling techniques commonly used in environmental and exploration geophysics. Students should be familiar with the basic principles of the methods and how they are used to solve real problems. They should know advantages and disadvantages as well as the limitations of the individual approaches. The course includes exercises in Matlab where the stduents both should lear, understand and use existing scripts as well as carrying out some coding in Matlab themselves. | ||||
| Content | During the first part of the course, the following topics are covered: - Applications of modelling - Physics of acoustic, elastic, viscoelastic wave equations as well as Maxwell's equations for electromagnetic wave propagation and diffusive problems - Recap of basic techniques in signal processing and applied mathematics - Potential field modelling - Solving PDE's, boundary conditions and initial conditions - Acoustic/elastic wave propagation I, explicit time-domain finite-difference methods - Acoustic/elastic wave propagation II, Viscoelastic, pseudospectral - Acoustic/elastic wave propagation III, spectral accuracy in time, frequency domain FD, Eikonal - Implicit finite-difference methods (geoelectric) - Finite element methods, 1D/2D (heat equation) - Finite element methods, 3D (geoelectric) - Acoustic/elastic wave propagation IV, Finite element and spectral element methods - HPC and current challenges in computational seismology - Seismic data imaging project Most of the lecture modules are accompanied by exercises Small projects will be assigned to the students. They either include a programming exercise or applications of existing modelling codes. | ||||

| 651-4104-00L | Geophysical Field Work and Processing: Methods | 2 credits | 3V | C. Schmelzbach, M. Grab, H. Maurer | |
| Abstract | The 'Methods' part of 'Geophysical Fieldwork and Processing' provides an overview over the most common methods used in Applied Geophysics. Theoretical and conceptual aspects as well as data acquisition and processing of the methods used in the other two parts of the course are introduced. | ||||
| Learning objective | Students should (1) acquire a basis knowledge on theory and working principles of the most common techniques in Applied Geophysics and (2) acquire the necessary knowledge to plan, conduct, process and document a near-surface geophysics survey. | ||||
| Content | The course is divided into four parts: 1. Introduction to the course held in the lecture hall (first lecture) 2. Online lectures and quizzes covering short reviews of the theory, techniques, acquisition and processing of: - Ground Penetrating Radar (GPR) - Electrical Resistivity Tomography (ERT) - Magnetic Surveying - Electromagnetic Induction Surveying - Seismic Refraction Tomography There will be a questions-and-answers session held in the lecture hall before the exam (second last lecture). 3. Practical exercise and field equipment demonstration (outdoor; location and date will be communicated during the introduction lecture). Participation in the practical exercise is a REQUIREMENT. 4. Written examination during the last lecture. A pass in this exam is a REQUIREMENT to continue with the second part of the course 651-4106-03L Geophysical Field Work and Processing: Preparation and Field Work. | ||||
