Development of Drilling and Production Technology for Deep Geothermal Resources

Abstract

Deep geothermal resources are believed to exist below already-developed shallow geothermal reservoirs. These currently unutilized resources are expected to contribute to the expansion of geothermal power generation capacity in the near future. To ensure that deep geothermal resources can be exploited safely, efficiently, and economical1y, NEDO is developing appropriate technologies. The content of the technological development in this project consists of the "development of drilling technology for deep geothermal resources" and the "development of production technology for deep geothermal resources". This paper outlines the progress of NEDO's technological development for exploiting deep geothermal resources.
