  • Methane hydrate dissociation accelerating and methane gas deriving system
    Patent number: 8474519
    Abstract: Warm water is pumped up by a pump from an underground aquifer present 1000 to 1500 m below the seabed, geothermal energy is caused to flow through a permeable layer below a methane hydrate layer, a dissociation boundary surface of an un-dissociated area of the methane hydrate layer is dissociated to generate methane gas, the methane gas is led into a production well from peripheral areas and through a gas inlet screen and caused to rise so that the methane gas is collected on the sea.

  • METHANE HYDRATE DISSOCIATION ACCELERATING AND METHANE GAS DERIVING SYSTEM
    Publication number: 20100132933
    Abstract: It is an object of the present invention to provide a deriving technique with economy and technical difficulty improved without depending on fuel consumption for a heat source when methane gas is derived from a methane hydrate layer. Warm water is pumped up by a pump from an underground aquifer present 1000 to 1500 m below the seabed, geothermal energy is caused to flow through a permeable layer below a methane hydrate layer, a dissociation boundary surface of an un-dissociated area of the methane hydrate layer is dissociated to generate methane gas, the methane gas is led into a production well from peripheral areas and through a gas inlet screen and caused to rise so that the methane gas is collected on the sea.
