About the Course:
This course discusses various methods of geology, geophysics and geochemistry used during exploration of geothermal or hydrothermal system
- Geology overviews various surveys used during geothermal exploration. Furthermore, it gives knowledge about alteration minerals, especially ones which are common in geothermal system.
- Geophysical study overviews various surveys used during geothermal exploration. It gives knowledge how to compile geological condition and geophysics anomalies and physical properties of rock to understand subsurface structure or reservoir.
- Geochemistry overviews various surveys used during geothermal exploration, type and distribution of geothermal fluids and interpretation of reservoir condition.
The aim of the course is to give an understanding of the geothermal system and geological methods and their application to identify a geothermal area, including its surface manifestation, within a volcanic area. Another main subject of this course is to understand various minerals commonly occurring in geothermal system, its type of alteration and how to use it to understand the behavior of reservoir.

- Advanced data processing of gravity and magnetic data
- Geo-electrical method I (VES, mapping/imaging)
- Geo-electrical method II (SP, MAM)
- Data acquisition and processing of magnetotelluric (MT) data
- Modeling of MT data
- Transient Electromagnetic (TEM) method
- Micro-earthquake (MEQ) method
This course covers all aspects of chemistry at geothermal fluid. It explains type, composition, origin and distribution of the fluids; and the effects of boiling, mixing and condensation to the composition of water. How to understanding of the reservoir condition is also given, followed by the behaviors of gas and stable isotope in geothermal systems. At last the course will point out on monitoring of production wells, including scaling formation and corrosively in production pipes, and environmental aspects.
