Six months ago,I would do a paper about the Hydraulic Fracture Technology in shale gas development.I add a discussion in the forum(see at http://gomarcellusshale.com/forum/topics/some-questions-about-the?x...Many enthusiastic people helped me,and gived me many usefull referances.Many of them were used in my paper.These days my paper Hydraulic Fracturing Technology and Application Analysis of Shale Gas were published on the Natural Gas Industry(Chinese core journals).At the end of this paper,I thanked the people who helper me,such as Jean Michel LeTennier charles meng   La_Man  David Pache and so on.Though you can't see this journal in USA.But I want to express my appreciation to these people.Thank you very much.

This is the paper' abstract below:

Abstract: Shale gas wells can get ideal production only after reservoirs reconstruction due to the
small porosity and low permeability of the shale. Hydraulic fracturing is one of the core
technologies, which has been widely used in shale gas development. Combining principles of
hydraulic fracturing technology and application examples of shale gas in foreign countries, this
paper analyzes the characteristics and applicability of a variety of hydraulic fracturing
technologies, which include Multi-Stage Fracturing, Water Fracturing, Hydrojet Fracturing,
Refracturing and Simultaneous Fracturing. This paper also analyzes the role of nature fracture
system and the fracturing fluid in hydraulic fracturing.  According to the cost of hydraulic
fracturing in shale gas well and technical characteristics, shale gas exploration and development in
China can be carried out from Refracturing in old wells and hydraulic fracturing in new wells at
present. The old wells which had shale gas shows through data review could be fractured by
modern hydraulic fracturing. The favorable reservoir over 1500 m or exploration shallow wells
could be fractured with Nitrogen foam. In reservoir between 1500 m and 3000 m , Water
Fracturing can be used, however, the reservoir below 3000 m can not be taken into consideration
at present.
