| Abstract | For the development of geothernal energy utiIization. equipment cost reduction is one of the most important factors. In Japan, the cost ratio of driIIIs for geothermal energy amounts to about of development cost. Achievement geothermal I s is a key factor for cost examples of 60-84% achievement ratio have been published in Japan. Kirishima Geothermal Project was divided into four development stages. For this established achievement targets for each stage. The attained achievement results were 88-92% against the planned ratio of 80 This is a very good result compared to the above ished f papers explain the the drilling results and refer to items to be solved in the future. |
