 Natural gas and one of the best sources of energy, and fossil fuels like oil and coal, are in the ground from the remains of plants and animals live and molecules that lived millions of years ago. Compound and natural gas has no color nor form nor smell. It was before the discovery of ways to use it burn in the air to get rid of it. There are natural gas to oil in the reservoirs located at depths ranging between one kilometer and two kilometers below the surface of the earth, and there alone in the depths of greater, and is therefore extracted from the earth in two forms:

1 - associated gas; there is a gas that is associated with crude oil and the laboratories Pferzh him. 2 - non-associated gas; there is a gas in a manner independent of crude oil and treat the plants and prepared for distribution  Among the most important features of natural gas that fuels an active and economically viable and less damaging to the environment. Natural gas is the fastest growing primary energy sources in the world during the last three decades, due to its characteristics and its advantages.

 Has grown the natural gas industry in Saudi Arabia, growth, and increased demand for them steadily beginning in Has become the Kingdom of Saudi Arabia occupies fourth place in the natural gas reserves in the world (after Russia, Iran and Qatar) confirmed reserves of 235 trillion cubic feet, while the longer the day of the first ten countries in the production. With the accession project to develop natural gas and oil in a gas network incited to the country's major processing power to be General of the Kingdom of Saudi Arabia has reached to around 9 billion cubic feet was standard cubic per day.

 Supports the natural gas industry Arabia today a number of key sectors such as petrochemicals, steel, cement, power generation, water desalination. The sales gas is distributed to these sectors as 40% of this consumption generates 21% is consumed in the manufacture of petrochemicals, fuel and valuable for the production of plastics and industrial chemicals, which are for 17% is consumed as fuel for sea water desalination plants, which is one of the most important sources of drinking water in the country, where Saudi Arabia is one of the largest states in per capita consumption of drinking water in the 14% is consumed for the petroleum industry, particularly in support of the Master Gas System, and lift capacity.

8% is consumed for other industries such as steel and cement. And contribute to an essential contribution of these sectors in the Saudi economy, they produce a cash stream of $ 25 billion, equal to 15% of GDP in the Saudi economy, and provide 35 thousand direct jobs and 150 thousand jobs related to the industry.

 Natural gas has become a daily need. It is widely used as fuel for cooking, heating and water heating. It is an effective fuel for power generation, especially gas turbine systems using high feasibility, playing an integral role for the production of clean electricity production high efficiency. It is very necessary for the desalination of water. And indispensable to the growth of the petrochemical industry Saudi Arabia, which has its production is currently about 10% of the world, using some petrochemical products in the manufacture of electrical goods such as condoms, files, sockets and cable-sheaths, etc., and in automotive parts such as door frames, windows and cut transmission, hydraulic brakes and frameworks and pieces of plastic and rubber industry, and home furnishings such as carpet types and linen bags and pillows and mattresses to sleep, and materials for the manufacture of textiles, underwear, shirts, coats, suits, and typewriters, book covers and photographic films, insulation, paint, solvents, soaps, detergents, and other things that countless

 Natural gas is one of the most important sources of global energy and presence in the land, as it accounts for 42 per cent of the total world energy currently in use upwards of 19 per cent in 1980, while the dependence on oil in the generation of global energy from 46 per cent in 1980 to 37 percent in Thus, the global demand for natural gas has doubled between the periods 1980 and The natural gas is also one of the most important foundations of modern industry, whether petrochemical or other. As this article from the strategic importance for each of the world, these countries are constantly searching and prospecting hard to raise their reserves of it.

 Natural gas consists mainly of methane, the simplest hydrocarbon gases, where the convergence rate of methane in natural gas 90 per cent. And natural gas (LNG) LNG. It seems clear that natural gas and Mosul through a network of pipes is different from natural gas (LNG) is simple because it contains nitrogen gas and carbon dioxide.

 Natural Gas: is a combination of materials that exist in Alhdrokrboneh reservoir rock Beneath the surface of the earth and is often the natural gas was with crude oil, either dissolved or floating on its surface and in this case is called this type of gas, "gas attendant." There are also fields that contain only natural gas and is the so- called "free gas" and all the components Alhdrokrboneh of natural gas is a kind of chained light flammable easily the presence of air and is a methane more components of natural gas abundant as the increase rate of 80% in most often followed by ethane Valbrooban Valbotan
