Geo-Electrical Method for Geothermal Exploration

Training Geo-Electrical Method for Geothermal Exploration

About the Course:
The geo-electrical methods are the most widely used geophysical methods to explore the geothermal resources. The geo-electrical methods study the physical property of rocks, i.e. electrical resistivity or conductivity which is directly related to the thermal phenomenon prevailing in the geothermal areas. This course will be focused on direct-current (DC) resistivity and magnetotelluric (MT) methods as primary geophysical methods for geothermal exploration. However other specific and related techniques will be discussed as well (e.g. Self-Potential, Mise-a-la-Masse, Transient EM).
The course will assume a basic knowledge in geology and geophysics, with possible extension to a more general audience with engineering background. The participants will gain the knowledge necessary to design and to plan cost-effective DC-resistivity and MT field program and to manage the survey.

Objectives:
The aim of the course is to give an overview of geo-electrical methods and their application for geothermal exploration. This course will introduce the participants to the concept of DC-resistivity and MT methods, basic data processing and interpretation issues as well as recent development in those aspects of the methods. There will be also discussion sessions on case studies of DC-resistivity and MT application whithin the geothermal exploration framework.
