Adopt new technologies, unconventional oil production is increasing rapidly.

In 2005, the then U.S. Vice President Dick Cheney (oil giant Halliburton's former CEO) and promoted by the vigorous lobbying, Congress passed the "Energy Policy Act" prohibits EPA using the "Safe Drinking Water Act "Control oil and gas extraction, eliminating the widespread use of  Hydraulic fracturing  and horizontal drilling technology is the biggest obstacle. German "international politics" bimonthly 2013 March-April issue publication Heinrich - Böll Foundation Chairman Ralph? Fox entitled "resource curse," the article states that "the rapid extraction technique leads recoverable oil and more and more natural gas resources. "

Using hydraulic fracturing technology, not only to re-develop old oil fields, but also to mass exploitation of unconventional oil and gas resources. United States, "Washington Post" Web site published in October 2011,ceramic ball chairman of Cambridge Energy Research Associates Daniel Yergin, entitled "Oil New World Order," the article describes, the use of hydraulic drilling techniques and hydraulic fracturing technology made from dense rocks More and more oil. In 2000, U.S. oil production is tight rock Nissan 20 million barrels per day by 2020 will reach 300 million barrels a day after, the equivalent of U.S. daily oil output of 1/3.

Harvard Business School published study reported that U.S. oil production of 800 million barrels from 2013 to 2020 of 1160 million barrels of foreign oil dependency has risen from 60 per cent in 2005 to 42% in 2012. U.S. "national interest" bimonthly web site in March 2013 introduced in the U.S. energy supply of oil from the Middle East accounted for only 14%. Citibank estimates that by 2020, U.S. oil production will reach 13 million barrels to 15 million barrels, which will assist in North America as the "New Middle East." International Energy Agency (IEA) predicts that by 2017,frac sand companies the United States will surpass Saudi Arabia as the world's largest oil producer. To 2035, the United States almost able to achieve oil self-sufficiency.

British "Financial Times" Web site in November 2012 issued a "explore: energy, security and reshape the Modern World," a book of Daniel Eugene entitled "U.S. Energy is changing the world," the article pointed out: "Although oil production has undergone tremendous changes, but even less dependent on energy imports can not get rid of U.S. geopolitical logic, they would remain closely connected with the entire world.
