Geothermal Engineering Co., Ltd.

History December 1976: Established company (former company name “Nichige Development Co., Ltd.”) October 1993: Changed company name to “Geothermal Engineering Co., Ltd.” December 2001: ISO9001: 2000 acquired July 2013: Opened Tokyo Office November 2017: Transition to ISO9001: 2015 In 1966, Matsukawa Geothermal Power Plant was born, the first geothermal power plant in Japan. Their company was established based on the exploration and sakui divisions of Nippon Heavy Chemical Industry Co., Ltd., which was involved in the development. Since then, they have been involved in the geothermal development survey of Matsukawa, Kakkonda, Mori, Matsuo Hachimantai, etc. for more than half a century, and have made a solid step in the Japanese geothermal industry as a pioneer of geothermal development and a comprehensive geothermal engineering company. It was. In the exploration department, analysis of geothermal reservoirs based on geological surveys, alteration zone surveys, fluid geochemical surveys, and other well surveys such as temperature, pressure, electricity, spinners, calipers, and ABI logging in the development stage They evaluate the amount of resources. After the construction of the power plant, in addition to evaluating the fluid behavior of the entire reservoir through various logging, fluid geochemical surveys, and tracer tests, they conduct reservoir simulation analysis as a geothermal reservoir management task. The Sakui Division owns three of the latest 3,000m class rigs (excavators) that have been recently updated, and excavate geothermal wells (production wells, reduction wells, survey wells). So far, it has been implemented nationwide, including the Matsukawa, Kakkonda, Mori, and Matsuo Hachimantai areas. In particular, they have a track record of construction in difficult tasks such as deep well drilling in Kakonda (depth 3,729m, temperature 500 ° C or higher) and high-tilt excavation in the Unzen Scientific Drilling Project (slope angle of about 74 °). By integrating both departments, they will respond to various needs from the initial development stage to the power plant construction stage and after the start of power plant operation.
