Shale gas set up the first 172 independent minerals cited concerns related parties

Weiyuan national demonstration area of ​​ shale gas  in the previous media coverage has been praised. But China Energy Network Research Center in July this block research shows that local feedback on shale gas results are not so optimistic, environmental protection, mineral rights, technology and policy issues involved in the local joint concerns. Feedback poor local environmental risks of shale gas in Sichuan, one of the biggest obstacle encountered, the local parties involved agreed that the complex topography of Sichuan, a large population and limited land and water resources, the environmental capacity is insufficient to large-scale exploitation of shale gas.Hydraulic fracturing Meanwhile, the perfect shale gas industry regulatory policy has not yet formed, in which the environmental sector awkward position, you can not fully play its regulatory functions in the field of environmental protection. Prior to the relevant countries have already carried out a comprehensive geological exploration blocks, the Ministry data show that the national total of 180 shale gas favorable area, total area of ​​1,110,000 square kilometers. But local Sichuan agreed that the relevant basis for shale gas geological exploration work is still not perfect, shale gas resource potential is still uncertain, can not distinguish between beneficial area is not conducive to commercial development of shale gas. Although Changning - Weiyuan block in China's first horizontal shale gas wells - Wei 201-H1 well fracturing has created 11 above the level of domestic shale gas well fracturing maximum number of segments, the highest pressure injection pump, single well with was the largest, the largest displacement construction, the longest continuous construction and many other records, the existing stable production are 10,000 cubic meters / day or so, and directly through the gas pipeline to neighboring towns. But local opinion still considers the exploitation of shale gas relative lack of core technology, there is no corresponding technical standards.frac sand companies In addition, for the establishment of the first shale gas 172 independent minerals involved parties have concerns about this. They believe that shale gas exploration and development itself has a high risk, requires high technical content and financial support. Set shale gas as an independent minerals will reduce barriers to entry for non-oil and gas companies will greatly increase their investment risk. On the environment, private enterprises often lack environmental awareness and capacity will increase environmental risks. Environmental, geological, technical, policy is not shale gas development bottleneck? Shale gas having gone through two vigorous bidding ceremony, supporting voice and the voices of doubt still come and go. Sichuan Changning - Weiyuan national demonstration area views shale gas shale gas to carry out further work has a pivotal significance. Environmental, technical, policy in the present situation, is the process of feedback shale gas out of the most difficult problems, the relevant experts have carried out some explanation. Environmental risks of shale gas issue, not only in China, the booming shale gas in the United States also suffered questioned. Relevant environmental experts believe that the reason why the United States but also in the huge challenge of shale gas continue to develop environmental risk, because the United States has a timely and effective response mechanisms environmental accidents. U.S. shale gas development environmental regulation in place, the exploitation of emerging environmental accidents will be the first time back to the U.S. Environmental Protection Agency (EPA) and quickly make a deal with the response, the formation of regulatory and respond to environmental accidents related policies and regulations. U.S. commercial exploitation of shale gas is not a long time, from the beginning of the explosive growth in 2006, counting only seven years, the U.S. team shale gas related environmental regulations are still being improved. In April last year, the United States issued a shale gas environmental regulations, require the use of shale gas in hydraulic fracturing technology to control air pollution, which is only caused by the United States against the exploitation of shale gas environmental laws and regulations promulgated by the first. China is still in the primary stage of shale gas development, environmental regulation on shale gas still has a long way to go.
