U.S. with "stones blue gold" move the world

shale gas, one pair of the general public is a bit strange term, and now more and more frequently in the media reports. American virtue hidden in the crevice of this successful commercial development of natural gas in their country set off a "energy revolution." Analysts predict that the revolution may even rewrite the pattern of world energy. In a way, shale gas determines U.S. foreign policy orientation and strategic focus.
"Crevice Blue Gold" has been forgotten and now into the core
International Energy Agency's annual report, so shale gas has once again become the focus of media.
This World Energy Outlook published last month reported that the shale gas revolution is fundamentally reshaping the U.S. energy market, and rewrite the pattern of world energy. It predicts, thanks to the successful development of unconventional oil and gas, to 2017, the United States will become the world's largest oil producer; 2020, U.S. natural gas exports will exceed imports; 2035, the crude oil exports exceed imports, the United States Energy imports from an exporter.
Shale gas formations in the free state is present in the shale in an  unconventional gas  resources. Relative to the "black gold" oil, natural gas because of its relatively clean is known as "blue gold", and shale gas were extruded rock crevices media called "blue gold."
Shale gas is usually distributed in the basin thick, widely distributed shale source rock formations. Shale is a sedimentary rock formed silt, hard texture. Since the technical difficulty of shale gas is much greater than the average natural gas, coupled with pre require a huge investment, input and output efficiency is not ideal, and therefore in the world has not been large-scale development.
With the continuous development of mining technology, which had been neglected for energy, and now seems to be the core of future energy. Experts estimate that global shale gas resources of about 456 trillion cubic meters,fracturing proppant may be greater than conventional natural gas resource potential.
U.S. Energy Information Administration released the "2012 Annual Energy Outlook," shows that the U.S. technically recoverable shale gas reserves of 13.6 trillion cubic meters. According to the current U.S. natural gas consumption calculations, which use about 100 years for the United States. U.S. Department of Energy has estimated that China's shale gas recoverable reserves of about 36 trillion cubic meters, at current consumption levels, enough Chinese to use 300 years.
