For the first time, an international research program involving the Department of the Interior's U.S. Geological Survey has proven that it is technically feasible to produce gas from gas hydrates. Gas hydrates are a naturally occurring "ice-like" combination of natural gas and water that have the potential to be a significant new source of energy from the world's oceans and polar regions. Today at a symposium in Japan, the successful results of the first modern, fully integrated production testing of gas hydrates are being discussed by an international gathering of research scientists. The international consortium, including the USGS, the Department of Energy, Canada, Japan, India, Germany, and the energy industry conducted test drilling at a site known as Mallik, in the Mackenzie Delta of the Canadian Arctic. This location was chosen because it has one of the highest concentrations of known gas hydrates in the world. The United States is committed to participating in international research programs such as this one to advance the understanding of natural gas hydrates and the development of these resources. Even though gas hydrates are known to occur in numerous marine and Arctic settings, little was known before the Mallik project about the technology necessary to produce gas hydrates.

Johnson, Hydrate Energy Int., 06/24/03 A methane hydrate is a cage-like lattice of ice, inside of which are trapped molecules of methane (the chief constituent of natural gas). In fact, the name for its parent class of compounds, "clathrates," comes from the Latin word meaning "to enclose with bars." Methane hydrates form in generally two types of geologic settings: (1) on land in permafrost regions where cold temperatures persist in shallow sediments, and (2) beneath the ocean floor at water depths greater than about 500 meters where high pressures dominate. The hydrate deposits themselves may be several hundred meters thick. Scientists have known about methane hydrates for a century or more. French scientists studied hydrates in 1890. In the 1930s, as natural gas pipelines were extended into colder climates, engineers discovered that hydrates, rather than ice, would form in the lines, often plugging the flow of gas.

Extractions: Marine and Coastal Geology Program Hydrates store immense amounts of methane, with major implications for energy resources and climate, but the natural controls on hydrates and their impacts on the environment are very poorly understood. Gas hydrates occur abundantly in nature, both in Arctic regions and in marine sediments. Gas hydrate is a crystalline solid consisting of gas molecules, usually methane, each surrounded by a cage of water molecules. It looks very much like water ice. Methane hydrate is stable in ocean floor sediments at water depths greater than 300 meters, and where it occurs, it is known to cement loose sediments in a surface layer several hundred meters thick. The worldwide amounts of carbon bound in gas hydrates is conservatively estimated to total twice the amount of carbon to be found in all known fossil fuels on Earth.

Formation of Fossil Fuels Fossil fuels formed from ancient organisms that died and were buried under layers of accumulating sediment. As additional sediment layers built up over these organic deposits, the material was subjected to increasing temperatures and pressures. Over millions of years, these physical conditions chemically transformed the organic material into hydrocarbons. Most organic debris is destroyed at the earth's surface by oxidation or by consumption by microorganisms. Organic material that survives to become buried under sediments or deposited in other oxygen-poor environments begins a series of chemical and biological transformations that may ultimately result in petroleum, natural gas, or coal. Many such deposits occur in sedimentary basins (depressed areas in the earthâs crust where sediments accumulate), and along continental shelves. Sediments may accumulate to depths of several thousand feet in a basin, exerting pressures up to one hundred million pascals (tens of thousands of pounds per square inch) and temperatures of several hundred degrees on the organic material. Over millions of years, these conditions can chemically transform the organic material into petroleum, natural gas, coal, or other types of fossil fuels. A.

Extractions: OTTAWA, ONTARIO (CCN Newswire via COMTEX) A seven-member international partnership, led by Natural Resources Canada (NRCan), has just completed groundbreaking research on natural gas hydrates in the Northwest Territories. Natural gas hydrates, a vast potential source of clean energy, are ice-like substances composed of water and natural gas that form in low temperatures and under high pressure. Many reservoirs are associated with deep permafrost of certain Arctic sedimentary basins and in marine sediments in coastal zones. NRCan's Geological Survey of Canada led a research project involving more than 50 scientists, which began in mid-December 2001, in the Mallik gas hydrate field in the Mackenzie Delta on the shores of the Beaufort Sea. Three research wells were drilled through the permafrost to carry out a diverse scientific program aimed at contributing to the evaluation of the potential and economic viability of gas hydrate production and to study the role of gas hydrates in climate change.

Extractions: Home Student Info Research About Us ... Directory Gas Hydrates Although gas hydrates contain hydrocarbons that are colorless, not all of them are white like snow. Some hydrates from the deep Gulf of Mexico are richly colored in shades of yellow, orange, or even red. The ice-like masses are beautiful, and contrast with the dull gray of deep sea muds. Hydrates from the Blake-Bahamas Plateau in the Atlantic Ocean can be gray or blue. Scientists would like to explain why hydrates show these colors, but so far there is little agreement on reasons. A number of different factors, including oil, bacteria, and minerals, are probably at play in producing the rainbow hydrates . Almost all gas hydrates are found by drilling in sediments at 10s to 100s of meters depth, but the gulf is different. The Gulf of Mexico is the best natural laboratory in the world for studying gas hydrates because they outcrop on the seafloor as mounds and can be easily sampled in sediments. Scientists aboard research vessels first found gas hydrates in the deep waters of the gulf in 1983 by taking core samples at sites where oil was naturally seeping out of the bottom. Hydrates have since been recovered in cores from water depths as shallow as 425 meters and at depths greater than 2000 meters.

Extractions: Gas hydrates are a class of materials that Sir Humphrey Davy first described in the early 1800s. They since have been defined as "an ice-like crystalline mineral in which hydrocarbon gases and non-hydrocarbon gases are held within rigid cages of water molecules" (Sassen et al. 2001). Described in this way, gas hydrates may not sound very interesting or important, but they are. If you hold a hydrate nodule in your hand and light it with a match, it will burn like a lantern wick. There is fire in this ice. People near the poles generally are familiar with gas hydrates because, like ice, glaciers and polar bears, they can exist on land at temperatures below freezing. They also can exist underwater above the freezing point at high pressures. When light natural gases (e.g., methane, ethane, propane, butane, pentane and their relatives) exist under either of these conditions, hydrates may form.

Extractions: Mr. Chairman and Committee Members, I am pleased and honored to be invited to testify before the Subcommittee on Energy and Environment regarding "S 330: Methane Hydrate Research and Development Act of 1998". I have conducted research on methane hydrates for more than 25 years focusing on both the properties of hydrates and the possible production of methane gas from hydrates. S 330 will not only provide an opportunity for outstanding scientific inquiry into the very frontiers of geophysics, oceanography and chemical engineering, but will also have important consequences for the future of the worlds energy supply and for the potential impact of fossil fuels on global climate change. What are gas hydrates? Gas hydrates are snow-like crystals that contain water and natural gas (mostly methane) which is virtually identical to the natural gas which, after processing, is burned in our homes. Gas hydrates are found beneath the earths oceans and beneath permafrost regions. If hydrates are brought to the ocean or land surface and exposed, the hydrates will melt and the gas will escape. About 160 cubic feet of natural gas is recovered from each cubic foot of hydrate. The goal of S 330 is to support research that will allow recovery of the gas in methane hydrates so that the gas can be used as an energy resource. Why are natural gas hydrates of interest?

Extractions: About Natural Gas What is Natural Gas? Natural gas is generally considered a nonrenewable fossil fuel. Natural gas is called a fossil fuel because it was formed from the remains of tiny sea animals and plants that died 200-400 million years ago. When these tiny sea animals and plants died, they sank to the bottom of the oceans where they were buried by layers of sand and silt. Over the years, the layers of sand and silt became thousands of feet thick, subjecting the energy-rich plant and animal remains to enormous pressure. Most scientists believe that the pressure, combined with the heat of the earth, changed this organic mixture into petroleum and natural gas. Eventually, the natural gas became trapped in the rock layers, like water becomes trapped in a sponge. Raw natural gas is a mixture of different gases. Its main ingredient is methane, a natural compound that is formed whenever plant and animal matter decays. By itself, methane is odorless, colorless, and tasteless. As a safety measure, natural gas companies add a chemical odorant called mercaptan (it smells like rotten eggs) so escaping gas can be detected. Natural gas should not be confused with gasoline, which is made from petroleum. History of Natural Gas The ancient peoples of Greece, Persia, and India discovered natural gas many centuries ago. The people were mystified by the burning springs created when natural gas seeping from cracks in the ground was ignited by lightning. They sometimes built temples around these eternal flames so they could worship the fire.

Extractions: Keeping you up to speed with news and events from around the world. Front Page UK Europe International ... News Releases Deep sea stores freshwater and natural gas Deep sea reservoirs of methane hydrates could be used to generate natural gas and freshwater. But technological advances are needed to pump out the gas and water without triggering submarine landslides. Methane hydrates are formed at high pressures and low temperatures, such as those found at the ocean bottom, where methane gas crystallises with water into lumps of ice. As methane freezes with ocean saltwater the salt crystallises out, leaving an icy mix of gas and pure water. Mega-tons of gas hydrates are found at the bottom of the ocean - at least twice as much in tons as fossil fuels and releasing less carbon dioxide when burned. The difficulty lies in accessing and transporting the hydrate, which melts and expands 164 times when brought to the sea surface. Hydrate instability in the reservoirs can also trigger submarine landslides, which can cause costly damage to pipelines and undersea cables. âMany technological problems need to be resolved, and these need a coordinated international effort,â says Nick Langhorne, science officer at the Office of Naval Research. Nevertheless, deep sea methane offers an extension to the lifetime of fossil fuels.

To show my gratitude for your visit of my page, let me tell you something about gas hydrates Gas hydrate looks very similar to ice. You can call it weird ice because you can set it on fire. But take a look at this picture . Hah! Surprised?! Gas hydrates are just so cool and interesting! The structure of gas hydrate is very different from ice. In gas hydrate, the water molecules arrange themselves around gas molecule to form a cage like structure You must have heard about Bermuda Triangle . Many stories relate Bermuda Triangle to UFOs. However, the most convincing explaination so far is that the dissociation of gas hydrates under the sea floor of Bermuda Triangle is responsible for the disappearance of ships/planes. As the gas hydrates dissociate, the gas will release from gas hydrates and float up toward the surface of the sea, which will decrease the density of sea water. Consequently the sea water is not able to support the ship anymore. The ship will sink straightly to the ocean bottom.
