Carbon Dioxide Capture and Storage (CCS) is a key technology to reduce carbon dioxide emission to the atmosphere and needed to be widely deployed in the world as early as possible. Mainly many developed countries are advancing research, development and demonstration of CCS. The Japanese Government is also conducting an investigation for CCS demonstration project in Japan. Since 2009, field surveys have been conducted at three candidate sites. An offshore pipeline route survey was carried out at the Nakoso-Iwakioki candidate site in 2009, a preliminary survey well was drilled at the Kitakyushu candidate site in 2010, and two 3D seismic surveys were carried out and two survey wells were drilled at the Tomakomai candidate site through 2009 to 2011. A final geological evaluation is being conducted for the Tomakomai candidate site and a demonstration plan will be presented to the Government as soon as the geological evaluation has been completed.

A pilot-scale CO2 sequestration test into an onshore saline aquifer has been conducted in Nagaoka-City, 200km north of Tokyo under cooperation of Research Institute of Innovative Technology for the Earth (RITE) and Engineering Advancement Association of Japan (ENAA).The aquifer, 1,100 meters in depth and 12 meters in thickness, is in shallower zone of Minami-Nagaoka gas field which is being operated by Teikoku Oil Co., Ltd. (TOC). An injection well and three observation ones were drilled in the site. CO2 of supercritical phase had been injected into a permeable zone in the aquifer with the rate of 20 to 40 tonnes per day. The injection started on July 7, 2003 and ended on January 11, 2005 with total amount of 10,405 tonnes. A series of monitoring method including time-lapse well logging, time-lapse cross-well seismic tomography, bottom-hole pressure/temperature measurement, fluid sampling and microseismicity monitoring have been successfully carried out to grasp the movement of injected CO2 during and after the injection. History-matching simulation had been performed to interpret the monitoring results. Long-term CO2 movement was predicted using the last model of history matching, implying the location and size of the CO2 to remain almost unchanged from those at the end of injection in the test area over a period as long as 1,000 years. The monitoring at the test site will be continued until 2007.
