U.S. dependence on foreign oil drop

Over the past 10 years, U.S. exports to Canada only 100,000 barrels of oil / day, while it imported 900 million barrels of oil a day, has been the world's largest oil importer. However, due to technical improvement and shale gas  development, U.S. domestic crude oil daily output reached 6.6 million barrels last week, this shift in the world's energy structure will have a significant impact.
When the 1973 Arab oil embargo against the West, the then U.S. President Richard Nixon had vowed in seven years to achieve energy self-sufficiency, but ultimately failed to achieve this oath.Hydraulic fracturing 1973 U.S. net oil imports accounted for 35% of demand, seven years after the import ratio rose to 37%.
By 2005, this proportion rose to 60%, U.S. imports of petroleum products also exceeded exports nearly 9 million barrels.fracturing proppant From that time since this difference has been steadily reduced, and in the November 2010 disappeared completely, which is the first time in decades. America's dependence on foreign oil also began to decline from 2005 until 2011 for 45%. Refined oil, the United States has been in the end of 2010 from a net importer to a net exporter.
2012 U.S. shale gas  production show explosive growth, is accelerating reduce U.S. dependence on foreign oil. 2012 YTD U.S. domestic oil production year on year growth of nearly 100 million barrels / day, higher than any other country. Statistics show that the first half of this year, U.S. domestic crude oil production has been able to meet 83% of domestic energy demand in 1991 reached its highest level.
U.S. President Barack Obama promised the U.S. in 2020 will be reduced by half the amount of crude oil imports, and increase efforts to develop crude oil and support the new energy. Since President Obama took office, the United States newly mined about 60,000 oil and gas wells, and this figure will continue to rise until 2016.
