"Shale gas revolution" to boost the U.S. economy

Shale gas is a special kind of unconventional natural gas, composition, uses the same conventional natural gas hosted in mudstone or shale, usually require a large  hydraulic fracturing  and horizontal well technology can be economically extracted. Shale gas development in the world's earliest and most successful countries are the United States. In the 1970s, the oil crisis in the United States for fear of depleted oil and gas resources, government-sponsored scientific and technological research projects shale gas, shale gas research to complement conventional oil and gas approach. 1981 first shale gas well fracturing success, breaking the shale gas exploration and development of technical bottlenecks. However, until the 21st century,Ceramic proppant the U.S. shale gas industry began rapid development. 2000 U.S. annual production of 12.2 billion cubic meters of shale gas by 2011 to achieve annual production of 172 billion cubic meters already, accounting for natural gas output of 1/4 or more. Today, U.S. crude oil, natural gas imports declined year by year, its own natural gas output and consumption are rising year by year to get rid of energy importer hat. Meanwhile, plenty of cheap shale gas on the market, not only reduces the price of natural gas, more to attract more enterprises "substitute gas for coal" and "gas oil" in reducing carbon emissions and promoting environmental protection has made important contributions. As a basic industrial raw materials, the application of the U.S. shale gas continuously enhance the competitiveness of chemical products, ethylene, polyethylene and other products competitiveness even more than in the Gulf region. Low production costs have prompted manufacturers to return to the continental United States,frac proppant accelerated the national employment promotion. By shale gas development, the United States to achieve the structural transformation of the energy of the gas, and promote environmental protection, reduce the gas energy prices and related social costs, and promote scientific and technological progress and employment, enhance U.S. national energy security factor. The United States is through the "energy revolution" reconstruction by the financial crisis hit the economy empire.
