Shale gas shortage environmental norms

Although commercial production is still zero, but the October 24, 2012 China's State Council Information Office published "China's Energy Policy (2012) White Paper," said the 2015 goal of  shale gas  production was 6.5 billion cubic meters. Relevant ministries plan also showed that China and strive to 2020 the annual output reached 60 billion -1000 billion cubic meters.
Eight years, China how to achieve zero to 100 billion cubic meters from the crossing? The international community can learn from the U.S. shale gas revolution, shale gas production in 2011 amounted to 170 billion cubic meters, while a decade ago,Ceramic proppant this figure was only 12.6 billion cubic meters, an increase of 14 times the decade.
U.S. shale gas revolution has helped to quickly lower the dependence on oil imports, while China shale gas recoverable resources comparable to the U.S., about 25 trillion cubic meters. Clearly, from the resources Strategically, China has sufficient reason to initiate shale gas revolution.
Shale gas is an organic-rich shales occur in their sandwich to adsorb and free state as the main mode of existence of unconventional gas, its composition is dominated by methane.
However, some environmental risks can not be ignored in China lie in front of shale gas revolution.
As the particularity of shale gas technology, requires about 10 times the normal amount of water oil and gas exploration, while the majority of shale gas resources in China located in water-poor regions. Greater water consumption also means a greater risk of fracturing fluid leakage and larger scale back drainage treatment, groundwater resources and surface environment whereby there may be contaminated.
In recent years, the environmental risk caused a lot of controversy in the United States, the world is also very concerned about. France therefore forbidden even to shale gas fracking.frac proppant Worrying is that in China, the environmental risks have not been widely discussed, there is no law to restrain these risks.
Because shale gas resources are more dispersed and other characteristics, the United States has thousands of small and medium enterprises involved in the exploitation. There are indications that China is also trying to introduce multiple investors involved in shale gas exploitation. The industry believes that such a pattern, such as beneath the constraints of the environmental risks could be multiplied.
