S., China began its shale gas research and exploration activity about 10 years ago. This paper briefed the history, state quo and future of shale gas development in the country. Factors that constrain the shale gas industry there include technology limitations, attitude of the government, environmental concerns and etc. The future of the shale gas industry in China depends heavily on how well these issues are dealt.展开更多

Shale gas production is expected to reach 4.5bcm by the end of 2015, with the construction of a 7.5 bcm production capacity. Over 700 shale gas wells have been drilled in China, mostly by the three state-owned oil companies. The most significant factors that led to the rapid shale gas development in China include the abundant shale gas resources, a relatively complete R＆D system, and strong support from various stakeholders （the central and local governments, oil companies, and the general public）. China has a long way to go for building a booming shale gas industry, because of many big obstacles in the way of shale gas development, including complex geology, high operation costs, incomplete infrastructure and technology constraints. Looking ahead, however, there are firm grounds for the projection of a bright prospect of China＇s shale gas industry , as a 20 bcm annual shale gas production is reasonably expected in 2020.展开更多

The technologies of drilling, production, fracturing using the supercritical CO2 in shale gas explo- ration are proposed, to increase the penetration rate, decrease the damage to formation while fracturing, and enhance the recovery of shale gas. It is believed that the huge economic benefits of shale gas exploration with the supercritical CO2 fluid will be obtained, and it also can initiate a new technology field of CO2 in the petroleum engineering.展开更多

The result of the ＂shale revolution＂ was billions of dollars in losses for oil exporters. The question is how this situation w＇ill be long-lasting or ＂shale bubble＂ will burst. The success of the shale revolution can be not only an economic win or economic defeat of the United States, the question is about reputation as a global political leader and the country＇s ability to solve the most difficult technological problems. Everything at stake to extend the ＂shale gas revolution＂ as it is possible longer, in time to prepare the conditions and technologies for a new energy revolution and to maintain the usual high level of energy consumption. The situation is further complicated by the introduction in the game of OPEC （organization of petroleum exporting countries） causing oil prices dropped below the cost of shale oil. The future of high technology in the production of oil depends on whether exporters and importers to negotiate the best price for oil, to ensure the sustainable development of the world economy.展开更多
