Delicate water issues

A  Hydraulic fracturing  in China engaged in the industry to introduce new financial reporters in recent years, a county in Shaanxi, conducted hundreds of cubic meters of hydraulic fracturing operations, has led the county was without water for several hours.
Fracking for shale gas exploitation mainstream technology, first used by the United States, China will follow.
Shale gas can not be mined by conventional methods, the special features of hydraulic fracturing, the drilling is completed, will be a special fracturing fluid into the well, the rock crevice remain open, and then rock shale gas recovery.
SINOPEC Research Institute of Petroleum Exploration and Development of unconventional energy technology support package of books King, vice president confirmed that  shale gas  water is roughly 10 times the water consumption of conventional natural gas. One engaged in hydraulic fracturing of Chinese technical staff, told reporters the new wealth, generally once a common horizontal well fracturing of natural gas to more than 1000 cubic meters of water, while the shale gas at 10,000 cubic meters of water above.
Industry experts believe that, in order to achieve the 2015 production of 6.5 billion cubic meters of planning, China has about 450-1380 shale gas wells, water demand is about 4.5 million -1380 million cubic meters.
In recent years, China's annual water consumption by about 35 billion cubic meters of industrial computing, the future can only shale gas water consumption accounted for 1.3% -3.9%.
Water consumption is not the whole story. As we all know, China is very uneven distribution of water resources. According to China Water Conservancy and Hydropower Research data, the North China Plain,frac sand Sichuan, Liaoning, Shaanxi, and Gansu Corridor Tianshan and other places is the key shortage areas, but these areas more with the Chinese shale gas resource-rich region overlap, such as Liaoning , Shaanxi, Xinjiang and Sichuan.
Subtly, China's first and second rounds of bidding shale gas blocks are located in southern China. Many industry insiders believe that the move is deliberately avoid water shortages were severe Northwest Territories. A production of shale gas in Sichuan in the sources, the current shale gas development in Sichuan do not yet have the bottleneck problem of water resources, but in the future to enter the large-scale development phase, "water situation is hard to say."
