Good post.Gas hydrates occur in many places worldwide, in deep-ocean or Arctic conditions where low temperatures and elevated pressures enable their formation.

the results of the Japanese/American test well drilling in Canada during 2008 produced commercial quantities of clean natural gas CH4 for over a week before being shut down. As a result the United Staates and Japan have signed a cooperative agreement to drill off the coast of Japan.

The Japanese propriatary technique consists of placing an inline turbo pump at hydrate level and pumping water in and gas out of the same line. If CO2 were to be injected into the downstream water this would displace the CH4 molacule within the clathrate without disturbing the physical structure. A really amazing process with little chance of damage to the hydrate field!
