抄録

The role of methane hydrate is discussed in demand situation of natural gases in Japan. Then, the necessity of methane hydrate enhanced recovery is shown in Japan project of methane hydrate. As one of the enhanced recovery methods, we are experimentally considering using carbon dioxide (CO₂). The latest results and its estimation show a possibility of using CO₂.
