The course discusses the main geophysical methods used for energy resource (oil, gas, and geothermal fluids) explorations and for environmental issues related to energy power plants.
In particular, the course aims at:
1) providing the basics of the seismological, geoelectrical, electromagnetic, gravity, magnetic, thermal, and radioactivity methods;
2) developing an operative knowledge of geophysical measurements to characterize physical aspects of rocks and of the geological structures related to energy resources.
3) building up the competencies related to the reconstruction of Earth's interior via simple physical relationships, and/or ad-hoc software and codes, based on the geophysical observations.
At the end of the course, the students will be able to:
- apply the learned techniques on synthetic/observed data;
- address autonomously and critically the study of geophysical phenomena and of the processes occurring in the subsurface.
- understand the appropriateness and applicability of the different methods for the specific problems connected with the geophysical exploration and characterization.
The students will also gain good control of the specific terminology to be able to understand the existing literature on this topic, and easily discuss with professionals.
In order to successfully attend the Exploration Geophysics for Energy Resources course, the student should have the basic mathematical knowledge generally provided by the Calculus (1 and 2) courses, and should have a good knowledge of the principles and methods provided by the Physics 1 and 2 courses.
The course will provide theoretical and practical knowledge of Applied Geophysics for Energy Sources Exploration. In particular, selected topics in Seismology, Geoelectrics, Electromagnetics, and Gravimetric methods will be discussed.
Introduction to geophysical methods [6 hours of theory]
Seismic methods [15 hours of theory, 8 hours of practice]
Electrical methods and Electromagnetic methods [10 hours of theory, 6 hours of practice]
Gravity method [6 hours of theory, 3 hours of practice]
Applications and Case Histories [6 hours]
Formal lectures: 46 hours; practical lessons: 17 hours.
Teaching activity will be mainly provided as formal lectures and practical lessons in the classroom.
Each lecture will systematically cover the main concepts and topics through slide presentations. The lecturer’s own research experience in the appropriate fields is brought into the lecturing sessions, where relevant.
References to significant textbooks and scientific papers will be provided as essential reading for each main topic discussed during the course.
To face the potential problems connected with the pandemic outbreak, the lectures will be held also on-line. Copies of the recorded lectures will be made available upon request. In addition, the more practical parts will be, in case, offered by means of the ICT tools available.
Verification of learning
The assessment of the acquired competencies consists of the submission and discussion of a research product by the student.
Due to the pandemic situation, the discussion might be held via the alternative ICT tools available.
The student is supposed to demonstrate a good understanding of the principles of the geophysical methodologies, and of the rationale and frameworks to apply them effectively.
The exam grade is in thirties.
In the exam evaluation, the exam grade is based on the following criteria:
1. level of understanding of the principles of the methodologies used in the student’s research product
2. level of critical thinking concerning the effectiveness and appropriateness of the solutions adopted in the student’s project
3. ability to extend the studied methodologies to different problems/contexts
4. exposition clarity
5. logic coherency in the presentation of the project
Meeting requirement no.1 is necessary to get a grade greater than 20/30. A grade greater than 27/30 can be obtained by the student who meets all four criteria.

As teaching support, all the slides to be used during the lessons will be provided at the beginning of the course. Then, some simple computer programs to interpret seismic data, electrical resistivity data, gravity data will be given. Finally, examples of exercises with their solutions will be discussed, together with samples of previous exams.
