Isotopic and Chemical Techniques in Geothermal Exploration, Development and Use: Sampling Methods, Data Handling, Interpretation - Edited by Stefán Arnórsson

Non-serial Publications

English STI/PUB/1086 ¦ 92-0-101600-X

351 pages ¦ 73 figures ¦ € 78.00 ¦ Date published: 2000


This publication, edited by Stéfan Arnórsson, is designed as an instructional manual of essential nuclear and complementary methodologies for a multidisciplinary approach to geothermal exploration development and monitoring. It provides comprehensive procedures for carrying out isotope and geochemical investigations of geothermal systems, i.e. sampling, analysis and data interpretation. It will be a valuable source of information for geoscientists working in geothermal, but also for those working in cold water projects, due to the similarity of methods and principles of investigations applied.
Contents: 1. Introduction; 2. Strategy in geothermal exploration, development and production; 3. Chemical reactions and chemical equilibria; 4. Reactive and conservative components; 5. Isotopes for geothermal investigations; 6. The source of chemical and isotopic components in geothermal fluids; 7. Geothermal manifestations and hydrothermal alteration; 8. Sampling of geothermal fluids: On-site measurements and sample treatment; 9. Presentation of analytical results, analytical precision and accuracy; 10. Geothermometry; 11. Mixing processes in upflow zones and mixing models; 12. Assessment of reservoir fluid composition from wet steam well data; 13. Hydrogen and oxygen isotopic fractionation during boiling; 14. Mineral saturation; 15. Estimation of aquifer steam fraction; 16. Monitoring of reservoir response to production.
