Progress of the Task of HDR Evaluation Under IEA Agreement

Abstract

The scope of the IEA Hot Dry Rock task includes HDR geothermal technology as well as other existing and new technologies that can be used for commercial heat extraction. The ultimate objective of Subtask D (HDR Evaluation Task) is to understand how much, how fast, and how long, geothermal energy can be extracted from an HDR reservoir system. Subtask D will clarify the types of methods, techniques, and tools that are effective for reservoir evaluation, and establish which evaluation methods will be most useful to develop new HDR sites. With this in mind, a questionnaire has been prepared to solicit information on reservoir evaluation techniques from core members of HDR task groups in each country and/or other concerned researchers.
