Study <strong>of</strong> Fracture Filling Methane Gas Hydrate<br />

• In MH21 project, target <strong>of</strong> exploration has been focused<br />

on sand layer pore space filling type <strong>hydrate</strong> in Eastern<br />

Nankai Trough forearc basin.<br />

• Fracture filling type <strong>hydrate</strong> is also developed around<br />

<strong>Japanese</strong> Islands. The most well studied area is the<br />

Eastern margin <strong>of</strong> Japan Sea.<br />

• They are developed mainly in fracture <strong>of</strong> mud layer, sea<br />

floor and shallow subbottom, and are accompanied with<br />

the upward fluid flow from the deep to sea bottom.<br />

• Scientific studies are not enough compared with the pore<br />

space filling type.<br />
