U.S. energy savior

Compared to conventional gas, shale gas mining technology is difficult, the cost is relatively high. For a long period of time, the industry is not all that large-scale shale gas  exploitation. However, from the 1990s onwards, with horizontal drilling techniques and fracturing techniques to improve and integrate applications, shale gas has enormous potential and industry knowledge economy gradually.

Just a few years ago, the United States has also spent heavily to import liquefied natural gas and the construction of docks, storage tanks and other large facilities, and now, the U.S. oil and gas company in the local discovered huge reserves of shale gas, large-scale exploration and production technology has matured . Thanks to large-scale production of shale gas, the United States in 2010, replaced Russia as the world's largest natural gas producer.

Shale gas extraction increased dramatically, is expected to reduce the U.S. dependence on imported oil,fracturing proppant and ultimately to achieve energy self-sufficiency and become a net exporter of liquefied natural gas. U.S. Energy Information Administration data showed that U.S. dependence on foreign oil from 60.3% in 2005, dropped in 2011 to 45% in the next decade the United States plans to further cut oil imports by one-third, is expected in 2035 comprehensive energy self-sufficiency in the United States rate will reach 87%.

Shale reservoir geological condition is superior, recoverable resources of shale oil and gas riches in conventional natural gas accumulated during the development of unconventional natural gas geological understanding and development of technology, proven natural gas gathering and transportation pipelines, combined for shale gas development in recent years, horizontal wells and multi-stage fracturing technology, technological innovation and breakthroughs, all contribute to the success of U.S. shale gas development an important factor. Meanwhile, the U.S. government introduced a package of unconventional gas development support policies, the active participation of small and medium sized professional firms and attracted a lot of foreign investment, and mature capital markets and financing channels, which gave the accelerated development of shale gas has created very favorable external conditions, making the U.S. shale gas development in the near future to achieve good results in the world of unconventional oil and gas development areas thriving.

The success of the U.S. shale gas development has brought changes in the pattern of world energy,Hydraulic fracturing but also inspired other countries in developing shale gas interest. Outside the United States, Canada, Australia, Germany, France, Sweden, Poland and other countries have begun to conduct research and exploration and development of shale gas.
