The gas molecules are trapped in water cavities that are composed of hydrogen-bonded water molecules, this type is called Clathrate.

| Summary: | Metha ne hydrate is a crystalline solid that is formed by water and gas. The gas molecules are trapped in water cavities that are composed of hydrogen-bonded water molecules, this type is called Clathrate. Methane hydrates is one of the alternative energy resources because of the massive quantities that spreads out globally in the world, especially in permafrost region and below oceanic sediment (Continental Margin). Hydrate form naturally under conditions of high pressures and low temperatures. Methane hydrate in Indonesia is identified in North Makassar Basin and Sunda Forearc Basin.<p>This final project describes various information related with the existence of methane hydrate in Indonesia. Hydrate was detected from the appearance of BSR (Bottom Simulating Reflector) on seismic section. BSR identified as the minimum hydrate bearing layer in the depth arround 300 m below the seafloor for North Makassar Basin and 600 m below the seafloor for Sunda Forearc Basin. In the North Makassar Basin, geothermal gradients averaged 0.047 oC/100m and the P-wave velocity arrounds 1.625 Km/s. In Sunda forearc basin, geothermal gradients is averaged 0.033 oC/100m with the P-wave velocity is arrounds 2.33 Km/s. The results analysis proved the existence of methane hydrate in Indonesia. |
