    The USGS has a globally recognized research program studying natural gas hydrates in deepwater and permafrost settings worldwide. USGS researchers focus on the potential of gas hydrates as an energy resource, the impact of climate change on gas hydrates, and seafloor stability issues.

    The USGS has assisted the Government of India in the discovery of large, highly enriched accumulations of natural gas hydrate in the Bay of Bengal. This is the first discovery of its kind in the Indian Ocean that has the potential to be producible.

    Gas hydrates demystified:
    • They are a naturally occurring, ice-like combination of natural gas and water. Generally they are found in oceans and Polar Regions
    • By nature, Gas hydrates are mostly methane (CH4). Methane gas hydrate is most stable at the seafloor at water depths which is below about 500 meters
    • They are considered as vast resources of natural gas and are known to occur in marine sediments on continental shelf margins
    • The total amount of gas available within the world’s gas hydrate accumulations is believed to greatly exceed the quantity of all known conventional gas resources

    Natural gas hydrates are a naturally occurring, ice-like combination of natural gas and water found in the world’s oceans and polar regions. The amount of gas within the world’s gas hydrate accumulations is estimated to greatly exceed the volume of all known conventional gas resources.
