China shale gas potential

According to the U.S. Energy Information Administration in 2011 for the 32 countries, 48 ​​shale gas basins of the world technically recoverable shale gas resources reached 6,622,000,000,000,000 cubic feet, of which China has 1,275,000,000,000,000 cubic feet of recoverable resources volume ranked first in the world,frac proppant followed by the United States and Argentina, its technically recoverable resources are 862 trillion cubic feet and 774 trillion cubic feet. In addition, Mexico, South Africa, Canada, Libya, Algeria, Brazil, Poland and France and other countries rich in shale gas resources.

Evaluation of shale gas resources that shale gas resources are mainly distributed in Sichuan, Xinjiang, Chongqing, Guizhou, Hubei, Hunan, Shaanxi and other provinces (autonomous regions and municipalities), these seven provinces, autonomous regions and municipalities accounted for shale gas resources in the country nearly 70% of the total.

According to the National Development and Reform Commission from 2011 to 2015 shale gas development plan, "Twelve Five" period will implement proven shale gas geological reserves of 600 billion cubic meters, recoverable reserves of 200 billion cubic meters in 2015 to achieve output of 6.5 billion cubic meters of shale gas m, and strive to 2020 the annual output to reach 600 billion to 100 billion cubic meters.

China's shale gas industry is still in its infancy, limited exploration activities, the availability of technical information is also small. So far, the Ministry carried out only once shale gas tender.Frac sand July 2011, on the four blocks of Sichuan and Guizhou to tender, the tender is limited to PetroChina, Sinopec, CNOOC, China United Coalbed Methane, Shanxi and Henan CBM companies extend the six companies. Sinopec and Henan CBM won one of the two blocks Xiushan nanchuan and the other two blocks due to lack of bidders and abortion.

Along with the increasing emphasis on shale gas resources, industry experts believe that the future of shale gas blocks may gradually relax the tender conditions. According to reports, in order to accelerate the realization of "five" goals, the second round of shale gas exploration tender will soon start, there are more than 70 companies expressed interest, one third of private enterprises.

December 2011, the State Council approved shale gas as Chinese new independent minerals, becoming China's first 172 kinds of minerals. Consider its own characteristics and Chinese shale gas exploration and exploitation of shale gas developments and foreign experience,ceramic ball the Ministry of shale gas will be managed by an independent minerals.

In recent years, the Ministry conducted a lead investigation and evaluation of shale gas resource potential and the favorable area preferably related work, and has made important progress. Some Chinese companies are also some of the energy distribution of concentrated areas of shale exploration and development of the technical aspects of a useful exploration. Meanwhile, the domestic research institutions to set up specialized agencies, began to study the mechanism of formation of shale gas, enrichment law, reservoir and storage conditions.
