Abstract

Shale gas has caused a change in the dynamics of gas market since development of horizontal drilling technic and hydraulic fracturing technic caused its commercial production. The commercial amount of shale gas is 187.5 trillions m3 so human can use it for 59 years and the amount will increase in the future. Several nations such as USA, Canada, China and Russia have more and more interested in shale gas as a futuristic major energy source. In accordance with this trend in the world, the amount of studying theses for development of shale gas have increased so their theses became important increasingly. The number of searched theses (1986 ~ The first half of 2013) is 3,468 and has increased recently. Among 89 nations studying shale gas, USA has 637 theses as No.1 in the world. 1,813 global studying institutes have studied shale gas; in the analysis result of several studying institutes, US geological survey institute was ranked as No.1 for the quality level of shale gas study and intensity of global cooperation.
