    All the best. Japan is also doing research on methane hydrates. Hope India also focuses on this field along with Thorium and solar. Right now world is dependent on just one major energy source i.e. Oil which distorts power balance of world giving too much control to arab sheikhs and their western overlords. This is one area where asian and african countries should cooperate with each others irrespective of their rivalries.

    ===================================

    China's first gas hydrate extraction successful

    China successfully extracted natural gas hydrate for the first time in the Shenhu area of the South China Sea on Thursday, China Geological Survey announced. This means China has become the first country in the world that can produce steady gas continuously.

    China Geological Survey (CGS), under the Ministry of Land and Resources, was in charge of the natural gas hydrate extraction test project, which started on May 10 and lasted for seven days and 19 hours.

    The CGS extracted natural gas hydrate from mines in the Shenhu area of the South China Sea, drilling 203-277 meters below the depth of 1,266 meters.

    By 10:00 a.m. (0200 GMT) on Thursday, the accumulated gas output had surpassed 120,000 cubic meters.

    The highest output in one day is 35,000 cubic meters, and the average output a day is about 16,000 cubic meters. Ninety-nine percent of the gas extracted is methane.

    The success of this project realized a major innovation of theory, technology, and engineering.

    ‍China's State Council expressed praise and recognition.

    What is natural gas h‍ydrate?

    Natural gas hydrates are ice-like structures in which gas, most often methane, is trapped inside water molecules.

    Unlike the ice we're all familiar with that's derived entirely from water, gas hydrates are in fact highly flammable, a property that makes these crystalline structures both an attractive future energy source as well as a potential hazard.

    If these sources of natural gas could be safely, efficiently and cheaply tapped into, gas hydrates could potentially displace coal and oil as the top sources of the world's energy.

    China found flammable ice, a kind of natural gas hydrate, in the South China Sea in 2007.

    International scientific circles have predicted that natural gas hydrate is the best replacement for oil and natural gas.

    We should get rid of this flammable fossil fuel BS. Our first and number one priority should be electricity from renewable sources as it is the way forward.

    We have huge reserves of methane hydrates in bay of Bengal. Last year India US and Japan together found them.toghether they can make technology and production viable while sharing development costs.

    Even with renewable we will need some dependable source for energy to fall back on. Hydrates are the way to go.

    Plus it's the road to poverty for arabs:hehe:

    What's gonna happen to these sand people when world will not rely on oil?
    They are sh8t at everything except iran. I think most of the sand country will invade each other and slaughter each other's population.

    Bruh I seriously hate repeating my post again and again. I said our emphasis should be on renewable source of energy and nuclear energy. I am totally against the use of coal for energy production.

    Coal will stay for 20-30 years . NITI aayog said so just recently. No can do.
    That is why it's important to find gas because gas burns much cleaner than coal. If we could leverage fire ice we can say goodbye to coal 10-15 years sooner than current scenario.

    They are not so fools to wait till the world run without oil ..they are exporting wahabism for this very particular purpose only the day the world wont need oil the Arabs can ask them to pay their respect to mecca and medina ...and still rule the world ..

    but personally i don t mind if those pigs gets slaughtered between them and perish o_O

    China's successful extraction of methane-hydrate (ie. natural gas in solid form) from the South China Sea seafloor is notable for the high average volume of 16,000 cubic meters per day and it was continuous over seven days. China achieved an astonishing maximum of 99.5% methane content.

    Baker Hughes Provides Completion System for JOGMEC Test Well Off Japan

    Baker Hughes announced that it participated in the first successful marine methane hydrate production test well offshore Japan on March 12, 2013. The test was conducted from a drill ship for the Japan Oil, Gas and Metals National Corporation (JOGMEC) in the Nankai Trough, approximately 60 km off the southeast coast of Japan, as one of the research activities in Japan’s Methane Hydrate R&D Program.

    Baker Hughes provided the completion system for the test well, which was drilled in approximately 1000 m of water into a hydrate formation approximately 300 m below the mud line.

    In 2009, Japan Drilling Co., Ltd., which is working for Research Consortium for Methane Hydrate Resources in Japan (also known as MH21), contracted Baker Hughes to conduct an engineering study to design a completion system that would reduce the pressure in the hydrate reservoir enough to break the hydrate down to methane and water, control sand during production, and acquire large amounts of downhole data to be used in subsequent reservoir modeling.

    The Baker Hughes system provided for this test well included zero degree centigrade qualification testing of standard products, a gravel-packed lower completion, a specially designed electric submersible pumping (ESP) system, a custom designed dual-string production packer, real-time electronic pressure/temperature and memory gauges, and a distributed temperature-sensing fiber-optic monitoring system. The ESP system was used to decrease reservoir pressure and included features that separated the methane from the water and enabled them to be pumped to the drill ship through separate production strings.

    As a result of the production test, Japan is the first country to have produced methane from hydrate formations below the seabed. MH21 estimates that methane hydrate formations in the eastern Nankai Trough hold as much as 40 Tcf of methane in place. Commercial production of methane hydrate reserves will require further research and a network of subsea wells.

    “Baker Hughes is excited that our technology and expertise played a vital role in this important project,” said Ian Ayling, Baker Hughes Director of Engineering, North Asia. “We look forward to working with JOGMEC on the next phase of their methane hydrate research.”

    Further having said that, Tech has been already available since last few years. But Chinese offshore industry is basically a mess. Safety and reliability is nowhere in comparison with west.

    'Combustible ice' ignites new energy race in Japan, China: The Nation

    In its editorial on 12 June, the paper examines how the recent developments on combustible ice, or methane hydrate, by China and Japan could impact the energy market.

    BANGKOK (THE NATION/ASIA NEWS NETWORK) - Big reports have come out of Japan and China over the past few days, in which it was suggested that commercial development of the globe's huge reserves of a frozen fuel known as "combustible ice" has gained another big step toward reality.

    The two countries have successfully extracted the material from the seafloor, a feat that was hailed as a potentially big milestone for energy revolution. To many, the reports are highly positive news; to others, there are causes for alarm.

    There are environmental risks involved if the world is to rely more on combustible ice. For one thing, some experts have warned that improper extraction processes, which could be rampant, could increase climate-changing greenhouse gases in the atmosphere. That, however, must not deter intensive efforts to research this kind of energy thoroughly. Combustible ice is said to be abundant enough to serve as a key energy source for up to hundreds of years.

    Methane hydrate, as combustible ice is technically known, has been found beneath the seafloor and buried inside Arctic permafrost and beneath Antarctic ice.

    The United States and India are also said to have research programmes aimed at creating technologies to capture the fuel. Extraction is reported to be very tricky, potentially environmentally harmful and highly expensive. In fact, the costs involved have discouraged previous efforts to tap up this source of energy.

    Its abundance, though, is one big reason why the world is optimistic about the developments in China and Japan. Estimates of worldwide reserves of combustible ice range from 280 trillion cubic metres up to 2,800 trillion cubic metres, according to the US Energy Information Administration.

    That is a lot bigger than natural gas reserves.

    Total worldwide production of natural gas was 3.5 billion cubic metres in 2015.

    Some experts can't see commercial-scale production of combustible ice just a few years from now, but China has already described its success as a major event in the world's "energy revolution." The Chinese optimism is not overstated, provided the rest of the world joins hands to find safe and cheapest extraction technologies.

    As for the more immediate future, methane hydrate offers Japan the chance to reduce its heavy reliance of imported fuels if it can tap into reserves off its coastline. China, meanwhile, has had to depend a lot on coal-burning power plants and steel factories that have threatened many with lung-damaging smog.

    World politics could change very significantly if combustible ice became a viable form of energy. Even without this, China is already pushing the United States hard in their race for world economic supremacy. Many academics studying conflicts in the South China Sea also see the growing value of combustible ice with considerable concern. Japan, meanwhile, could bounce back big time politically and economically.

    International politics may hinder combustible ice from the research processes to possible commercialisation of it. To de-politicise this form of energy, especially if its value rises, might be easier said than done, but the world must try. Energy, after all, is not just for superpowers. Small countries and ordinary people can all benefit from relatively cleaner, cheaper and more abundant sources of energy. This simple fact about energy has been under the shadows of superpowers' politic plays for a long time, and the latest news about combustible ice has everyone asking a big question of whether that can change or not.

    After all, this was the motivation for claiming the South China Sea. I always thought what is so important about this region that the parties are squabbling over it?

    280 trillion cubic metres is a lot of energy.
