Hydraulic fracturing method with nond

Fracking bring to the United States the greatest wealth is the "energy independence", the empty slogans of the past two years, the slogan of 30 years looks increasingly realistic, U.S. crude oil production in 2012 hit 20-year high dependence on foreign energy sources to 30 % or less, the benefits of energy independence to bring the United States is real.
On the one hand at the global strategic level, entangled in the Middle East for nearly 30 years, the United States finally had to get out of the condition, in 2012 the U.S.

strategic plan explicitly next 10 years, the Asia-Pacific as a strategic center of gravity is no longer invest a lot of effort to maintain a stable situation in the Middle East .
The past three years, whether the Jasmine Revolution, Syria civil strife, or Israeli-Palestinian conflict Iranian nuclear crisis, the United States can opposition headquarters, utter words then calmly observing European and Russian trade-off embarrassment. In addition, oil and gas resources, the United States and Europe, Japan and South Korea successfully enhance the centripetal force. 2012 Obama repeatedly hinted at the possibility of natural gas exports to Japan, followed by Japan's two prime ministers will seek U.S. gas exports as an important foreign policy objectives, one of the many issues had to accept the American threat. But today, the United States remains ambiguous on the issue
of natural gas exports, eventually forcing Japan to develop their own combustible ice. Even so, Shinzo Abe, has not yet given up, on several occasions since the beginning been urging the U.S. to honor gas export commitments, while Obama is still vague.
On the other hand, the U.S. oil and gas prices are low to the economy brought more support, 2012 U.S. crude oil and natural gas prices were lower than the global average of 70 percent and 20 percent, according to estimates, only the low price of natural gas annually give U.S. economy about $ 100 billion in benefits, let alone through the low oil prices on Canada's "resource plundering." Cheap energy in the past two years has attracted, including chemical, rubber and fertilizers, including many energy-intensive industries return to the U.S., the United States on a global scale also spared no effort to sell this advantage, since the beginning of U.S. Ambassador Gary Locke in multiple where low energy prices constantly stressed that the U.S. investment opportunities. In addition, the rapid growth of oil and gas production but also for the oil and gas industry has always been not wait to see Obama offers new financial breakout of the road, in his second term financial planning, the oil and gas industry, the U.S. government will provide $ 300 billion of revenue a new source, Although the plan was consistent with oil and gas industry and Republican opposition, but the development of shale oil and gas remains the U.S. to get rid of perennial budget deficit provides a new possibility.
Although the prospects look quite good, but the exploitation of any resources are inevitably bring destruction of natural resources, for the  hydraulic fracturing  method of this relatively new technology, the more serious the problems faced. For now, there are two major fracking hazards, first, groundwater pollution, and second, geological disasters. As a result, fracking has caused controversy in many countries, in June 2011, the French first legislation prohibiting the use of fracking,  Hydraulic fracturing  test even the most countries in Europe have been banned in industrialized mining basically impossible. Currently, only the United States' strong ally "British picked up the pace of economic recovery in the oil and gas industry as a new driving force, not only to promote fracking to enhance gas production, but is hoping once again become the North Sea oil and gas splurge big country.
Each hydraulic breakers are hydraulic fracturing takes a lot of water, according to statistics, the U.S. single-port shale gas wells average water consumption of 20 million tons. The fracturing fluid is added a large number of chemicals is injected directly into deep underground, although the depth of 1500 meters above does not directly groundwater crisis, but in the long term, gradual penetration of chemicals will cause great pollution. As a result, Chevron and Exxon and other oil giants are on fracking cautious. In Europe, in addition to America's "old boy" footsteps outside the UK, continental European countries still have not let go of basic hydraulic fracturing ban, resulting in the shale oil and gas development is still at a relatively backward technology level. Furthermore, because of over-exploitation of groundwater, oil shale mining areas there is a large area of ??groundwater gob, and then continue to exert a high pressure underground will bring uncertain geological damage, broken rock and East are more likely to trigger an earthquake sex. Since last year, a series of rare geological disasters, including last year in October and December occurred in Dallas earthquakes occurred in Ohio are accused of hydraulic fracturing triggered.
March 26, Oklahoma State University and Columbia University joint research projects show that Oklahoma's largest earthquake in history, November 2011's 5.6 earthquake caused by Hydraulic fracturing . Their data also show that in 2009, before Oklahoma number of earthquakes on record only 50 times; But since the massive hydraulic fracturing used in the state after 2010 alone there have been 1,047 times smaller earthquakes. From the data, hydraulic fracturing and geological disasters relationship seems very obvious, but the U.S. government has chosen an evasive attitude. In this research project was made public, the state's environmental protection department said the quake was still insist
generated from natural causes, and independent oil and gas exploration.
Then in April 10, standing on the side of the hydraulic fracturing method support given to respond decisively British academia, Durham University study showed that although the geological structure of  hydraulic fracturing  on impact, but not a major earthquake inducing factor, adding that the There are records of the earthquake, only three times caused by hydraulic fracturing, hydraulic fracturing on impact came in mining geology, geothermal and underground water after should not worry too much.
