ADVANCES IN ISOTOPE HYDROLOGY AND GEOCHEMISTRY FOR GEOTHERMAL RESERVOIR MANAGEMENT THROUGH INTERNATIONAL COOPERATION

摘要

Isotope hydrology and geochemistry have been widely applied in geothermal reservoir management in the past decade, which was made possible by the joint efforts of international organizations and participating institutions as well as individual scientists through effective international cooperation. Major progress has been made in understanding of the origin of acid fluids in geothermal reservoirs, in solving particular technical issues in various types of geothermal exploration programmes in different continents, in improving analytical quality of geothermal water chemistry through inter-laboratory comparison exercises and training, as well as in establishing comprehensive monitoring programmes for sustainable development of geothermal reservoirs. Regional and inter-regional cooperation projects offered good opportunities for transfer of know-how and technology through training courses and site demonstration. In view of the current situation when the world is faced by a major common task to mitigate climate change, it is more necessary than ever for countries to work together to increase the contribution of geothermal energy in national energy mix through promoting R&D and transfer of technology for a cleaner and safer world.
