Research On Energy Return On Investment Of Oil And Gas Supply In China

In the context of China’s oil and gas supply gap gradually increased,selecting the appropriate and effective way of oil and gas supply has become a major strategic issue in China.At present,there are a few researches on this issue,but most of these studies are based on the conventional methods of technical and economic analysis methods(such as input-output analysis).And they are lack of systematic and comprehensive logic.From a net energy perspective,this paper makes a comprehensive analysis and solution to the above problems by using the method of energy return on investment(EROI).Firstly,this article calculated the EROI of conventional oil and gas production from the industrial level,and improve the method of calculating EROI from the enterprise level,which was applied to the CNPC,Sinopec,CNOOC,Yanchang.Secondly,the EROI of the unconventional oil such as shale oil,heavy oil,coal-to-oil and biodiesel was calculated by using Fushun kerogen oil project,Liaohe oilfield’s heavy oil production,Shenhua coal-to-oil project and CNPC’s Nanchong biodiesel demonstration project as an example.The EROI of unconventional natural gas such as shale gas,coal seam gas,tight gas and coal-to-gas was calculated by using Fuling shale gas field,Qinshui coal seam gas field,Sugeli tight gas field and Datang coal-to-gas project as an example.Thirdly,build a more complete EROI calculation framework of imported oil and gas,and calculate the EROI of China’s imported oil and natural gas from different countries.Finally,according to the results of EROI analysis for China’s oil and gas industry,this article puts forward some suggestions to promote the development of China’s oil and gas supply effectively.
