Current and Past Project

Project on Ito Natural Analogue for CO2 Storage, Project INAS:
Safety and environmental assessments during and after CO2 injection are important for geological CO2 storage. It is required to set up safety guideline and to evaluate long-term environmental changes. Study on environmental changes between past and present geological phenomena is also essential for geological storage. However, direct measurements during long-term changes are difficult, because the diffusion and dispersion rates of CO2 are expected to be small rate and the evaluation period is sometimes needed more than 1,000 years. One of possible answers for this problem is an approache by a natural-analogue study that carries measurements at relatively shallow sediments.
To achieve the purpose of the research, Kyushu University shall collaborate with Korea National Company in the research on production system for huge reserve of heavy oil in South America.
During the research period, the research activities specified in Steam-EOR to produce heavy oil shall be conducted and propose the production system for KNOC.
A new process of hot water injection for gas-production (hereinafter HWIG) in order to produce methane gas from methane hydrate layers using dual horizontal wells has been studied. The methane hydrates reserve under sea bottom in 500 to 700 m in sea depth around Japan, such as Nankai-trough, are expected to be next-generation natural gas resources. The methane hydrate in the layers is sherbet-like solid and non-mobile against pressure difference, however, methane gas may be produced by giving heat to enhance hydrate decompositions by the HWIG process using horizontal wells that is similar system to the SAGD process with a reverse vertical positioning of two horizontal wells. The aims of present experiments were to observe the production characteristics, dissociation rate of methane hydrate and heat transfer phenomenon at interfaces between hot water and the hydrate zone. Present numerical modeling also involves gas production rate by dissociation of methane hydrate layers with four pairs of dual horizontal wells and developing a field scale model. The process has the possibility to recover the methane hydrates economically efficient and environmentally friendly by considering total system gas production and co-generating electric power generation system.
For the most part, carbon resources such as petroleum satisfied 20th century’s needs in energy and materials. However, the recent rapid economic growth of developing countries, primarily in Asia, is causing a grave shortage of resources. warming. In this project, I will enhance CO2 storage system development, especialy, CO2 injection into coal seams as a member of G-COE "Novel Carbon Sciences", Kyushu University.
CO2 injection into coal seams may enhance production of coal bed methane and make CO2 sequestration by adsorption of CO2 instead of CH4 on numerous microscopic pore surfaces in coal. The sealing of CO2 gas in coal seams assures by cap rocks that keeps CH4 gas in the seams.
It has been clarified that adsorption capacity of carbon dioxide in coal is roughly two times more possible than CH4 based on some laboratory experiments. By utilizing this mechanism, it is expected that CO2 is possibly sequestrated into coal seams by replacing coal seam methane gas with CO2 gas. The coal seam methane gas is comparatively clean energy which is abundantly included in Japanese coal seams. The Japanese demonstration project for CO2 sequestration into deep coal seams has been proceeded by the Japanese government, METI. The reserves of un-mined and non-economical coal seams, which are located in mainly the Hokkaido and Kyushu districts in Japan, have been estimated as about 10 billion-ton. Thus, it is also expected that there is a potential of CO2 sequestration into coal seams as about 5 trillion m3.
In this study, basic physical characteristics of coal specimens(core and crushed samples) on gas permeable flow and adsorption capacity of CO2 in coal seams necessary for establish a numerical model were measured. For example, sample sizes in evaluating CO2 gas absorption speed and permeability, etc. of the coal specimens are mentioned. Furthermore, Temperature analysis of the CO2 injector for super-critical conditions has been carried out in order to investigate bottom hole temperature and pressure.
Thermal production systems from ｎｏｎ-ｍｏｂｉｌｅｆｌｕｉｄｒｅｓｏｕｒｃｅｓａｔｌｏｗ temperature range with dual horizontal wells have been investigated with Prof. Policar, Univ. of Alberta, Canada.
