North American tight oil development prospects can be expected

Natural gas prices continued to slump in the United States under the influence, more and more companies are discovering dry gas business has been difficult to maintain profitability requirements. Meanwhile, in 2008, the international oil prices continued to rise, shale gas development technology in the tight oil development application have been successful, the operating companies are finding that even the moisture in tight oil production can achieve higher returns. In view of this, some companies began to cut jobs  shale gas  business, to put more money and energy into a dense liquid hydrocarbon-rich zone. In early 2012, in the United States engaged in the dry gas drilling rigs from 80% the proportion dropped to about 30%, while engaged in drilling activities related to oil production rig count proportion from 20% to 70%. North American tight oil rich reserves of tight oil is currently the world's most successful regional exploration and development, the main zone of tight oil Bakken, Eagle Ford, Niobrara, Utica, Wofu Kan, etc., but has invested large Only the scale of the development of North Dakota's Bakken and South Texas Eagle Ford, which is currently the main producing areas of the United States tight oil. According to the U.S. Energy Information Administration (EIA),ceramic ball as of November 2011, the United States of tight oil production of nearly 90 million barrels / day, compared with the beginning of 2009 to 25 million barrels / day increased nearly three-fold, of which approximately 84% came from Pakistan Ken and Eagle Ford shale area. Wood - McKinsey October 2012 predicted that the density of the United States in 2012 is expected to reach 150 million barrels of oil production / day level, representing approximately 24% of total oil consumption; 2020, its tight oil production and the proportion of will increase to 410 million barrels / day and 45%, Bakken and Eagle Ford production growth is still the main force. Canada's tight oil areas are mainly distributed in the Western Canadian Basin and the Appalachian Mountains in eastern regions, but tight oil production started late. 2005, by the high oil prices as well as horizontal wells and hydraulic fracturing techniques to promote successful commercial application, the company began operations in Canada involved in tight oil production. 2011, the Canadian tight oil production of about 14 million barrels / day by 2020 is expected to increase to 45 million barrels / day. Although the current tight oil exploration and development in Canada in the early stages, but on the tight oil in terms of the relevant basic research, Canada has done in many ways more detailed than the United States. Bakken / Aike Xiao tight oil mainly distributed in Canada, Saskatchewan, Manitoba and Alberta,frac sand Canada, is the earliest start tight oil production regions. United States Geological Survey (USGS) assessment said Canada's tight oil Bakken group can be as high as billions of barrels of recoverable reserves. Tim Carr tight oil zone is mainly distributed in Alberta, tight oil resources of the area of ​​10 billion to 30 billion barrels. As of 2011, the total proven oil reserves of 1.3 billion barrels of dense, tight oil production of about 40,000 barrels / day, is second only to the Bakken / Aike Xiao dense Canada's second-largest oil producing areas. Viking tight oil zones in Alberta and Saskatchewan are distributed, as of 2011, the district announced tight oil resources of 5,800 million barrels, yield about two million barrels / day.
