Methane Gas Hydrate
GSJ Symposium on Methane Gas Hydrate on June 10, 1996
Program in Japanese
Basic properties of Methane Gas Hydrate
- Physical properties compiled by Prensky (1995). Tables are designed with table tag of HTML2.
Synthetic Methane Hydrate
Methane Hydrate is formed in the very low temperature as permafrost region and high pressure - low temperature as deep sea condition.
Synthesized methane hydrate in GSJ laboratory within high pressure apparatus by T. Maekawa, GSJ, is burned as the following images.

Gas Hydrate BSR?
The following image shows Bottom Simulating Reflector (BSR) on the seismic reflection profile taken by USGS. This kind of BSR is believed as the base of gashydrate layer which shows more consolidated physical property than the deeper normal sediment.
Visit a page for the introduction to the Seismic Method.
Gas Hydrate BSR?
Messoyakha Gas Field, the first commercial hydrate deposits?
Messoyakha Gas Field (References) is reported as the first and only commercial methane gas deposits which produce gas from methane hydrate by Makogon, 1984.
Read an introduction to the Messoyakha Gas Field and the short record of the visit to the field, 1995.
