Present Status and Future Plans of The Ogachi HDR Project

Abstract

CRIEPI started the Ogachi project in the northern part of Japan in 1986, to determine the feasibility of an HDR geothermal power plant based on a multi-layer reservoir. During the past fifteen years we have developed technologies for surveying underground resources, forming multi-layer reservoirs and evaluating those reservoirs in a 1.7 billion yen study. Future plans include the development of a lifespan evaluation method, the improvement of production rates and finally, the establishment of an actual HDR power plant.
