A Summary of Results of the IEA Task Activities of Deep Geothermal Resources

Abstract

The IEA task of Deep Geothermal Resources started in 1997 as a four-year collaborative program with participation by five countries: New Zealand, the UK, the USA, Switzerland, and Japan, and one international organization (EC) under the IEA Geothermal Implementing Agreement GIA. The task consists of three subtasks: A) Exploration Technology and Reservoir Engineering; B) Drilling and Logging Technology; and C) Material Evaluation Program. The task activities are carried out under the leadership of the task and subtask leaders designated and approved by the Operating Agent (OA) and Executive Committee, respectively. The New Energy and Industrial Technology Development Organization (NEDO) is acting as OA, and is responsible for organizing task meetings, workshops, and field trips in collaboration with the participants. Information networks on each subtask were established and an official web site was opened in order to exchange information among the participants. Several kinds of data related to deep geothermal resources have been collected and stored on the web site. In accordance with the work programs, the OA held four technical sessions and conducted three field trips to the USA, Mexico, New Zealand and Italy.
