First successful gas extraction from frozen methane deposits


Japan has successfully extracted natural gas from frozen methane hydrate deposits under the sea, in the first example of production of the gas offshore, officials said on Tuesday. This is the milestone  and could be a step toward potential commercial production, though the costs of extracting gas from the seabed are much higher than for other forms of production.

Japaneese scientists used a specialistic technology relayed on reducing pressure in the underground layers which hold the methane hydrate 1,330 metres below the sea surface and then they dissolved it into micture of gas and water. In final step They were collecting the gas through a well.

“Ten years ago, everybody knew there was shale gas in the ground, but to extract it was too costly. Yet now it’s commercialised” said Ryo Minami, director of the oil and gas division at Japan’s Agency for Natural Resources during the performance, compared shale gas to frozen methane resources.

Methane hydrate is a form of methane gas frozen below the seabed or in permanently frozen ground called permafrost.  ‘Frozen methane’ may be compared to ice but burns like a candle if a flame is applied.
