Horizontal effects in fracturing operation of coal bed methane in Qinshui,Shanxi Province

Li Mengxi,Zhang Cong

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 16-19

Abstract:

This paper describes horizontal effects of CBM (coal bed methane)fracturingfractures have adverse effects, including reduced production flow rate, depletion, and watering during fracturingThis discovery shows that the horizontal compression of fracturing could have adverse impact on productionof adjacent wells, and fracturing designer should be aware of it.

Quantifying and mapping spatial variability of Shanghai household carbon footprints

Shangguang YANG,Chunlan WANG,Kevin LO,Mark WANG,Lin LIU

Frontiers in Energy 2015, Volume 9, Issue 1,   Pages 115-124 doi: 10.1007/s11708-015-0348-8

Abstract: Understanding the spatial variability of household carbon emissions is necessary for formulating sustainable and low-carbon energy policy. However, data on household carbon emissions is limited in China, the world’s largest greenhouse gases emitter. This study quantifies and maps household carbon emissions in Shanghai using a city-wide household survey. The findings reveal substantial spatial variability in household carbon emissions, especially in transport-related emissions. Low emission clusters are founded in Hongkou, Xuhui, Luwan, Jinshan, and Fengxian. High emission clusters are located in Jiading and Pudong. Overall, the spatial pattern of household carbon emissions in Shanghai is donut-shaped: lowest in the urban core, increasing in the surrounding suburban areas, and declining again in the urban fringe and rural regions. The household emissions are correlated with a number of housing and socioeconomic factors, including car ownership, type of dwelling, size of dwelling, age of dwelling, and income. The findings underscore the importance of a localized approach to low-carbon policy-making and implementation.
