Shale gas today, tomorrow is the shale oil?

Shale gas, which is located in mudstone or shale in the carbon to adsorb or free state as the main mode of existence of gas accumulation, its chemical composition is mainly methane.  shale gas  revolution began in the U.S., although the United States was first discovered in 1821 and use of shale gas, but the real substantive breakthrough, it is the 1970s after the thing.
The last century, 70 years ago, the U.S. natural gas price controlled upstream continued losses. First, on the part of the United States in 1978, the wellhead price deregulation, since the deepening of the process of the natural gas market, deregulation, the large number of companies into gas fields.
The 1970s oil crisis, also prompted the U.S. government and companies to accelerate development of domestic oil and gas resources, including shale invest a lot of money for gas,Ceramic proppant including unconventional oil and gas technology.
In the 1990s, early leader in the field of shale gas in horizontal drilling technology Michel breakthrough, and then mastered the big oil and hydraulic fracturing technology, into the 20th century, the exploitation of shale gas gradually began to flourish and to attract major oil companies through mergers and acquisitions involved in shale gas development.
In the technology matures at the same time, the exploitation of shale gas costs continue to decrease, but until 2002, shale gas in the economy still has an edge, it is difficult to achieve large-scale production.
After 2002, the U.S. natural gas prices rose sharply, the U.S. company increased shale gas exploration and development, and promote the development of shale gas constant breakthroughs in key technologies and applications.
30 years of technology experience and previous experience, since 2006 the U.S. shale gas production began to grow substantially.frac sand In 2000, the U.S. shale gas production accounts for only 1% of the amount of natural gas supply, and by 2010, this proportion is as high as 23%.
2011 U.S. shale gas production reached 180 billion cubic meters, accounting for 34% of U.S. natural gas production.
Meanwhile, in 2009, U.S. natural gas production reached 624 billion cubic meters, the first time over Russia became the world's first producer of natural gas, has since been maintained in this position. 2012 U.S. production of 681 billion cubic meters of natural gas, natural gas production is the world's fastest growing countries, more than Russia's second-largest natural gas production of 90 billion cubic meters more.
