Economic Evaluation Of Shale Gas At Lower Silurian,upper Yangtze Region

In the21st century, Shale gas is a huge potential for unconventional natural gasresources, It can serve as an important complement to conventional energy sources,which can effectively alleviate the pressure on the world’s energy. Currently, fordomestically,the exploitation of shale gas is not only an opportunity but also achallenge. Now the domestic shale gas resource utilization are in a stage ofdevelopment.Although the current reserves of shale gas is very large, the developmentof shale gas resources with high technical requirements.It requires a lot of capitalinvestment and personnel utilization. Therefore, for shale gas exploration anddevelopment, the economic evaluation of shale gas has a very important practicalsignificance.Upper Yangtze region is an important producer of shale gas resources in ourcountry. For ease of local jobs and economic development, etc.,development of shalegas is of great significance. Simultaneously,it can relieve the pressure of increasinglytense energy, for the development of new energy direction.In this paper, relying on the projects which is PetroChina2011key scientific andtechnological projects undertaked by Langfang Branch of PetroChina—The sub-topicsof The Preferred and Evaluation of Shale gas favorable target area at our key areas ofthe South—The Preferred and Evaluation of Shale gas favorable target in UpperYangtze key areas. In the process of doing the project, have get the first-handinformation,and favorable target areas for shale gas were optimized and evaluated.In this paper, a preliminary technical and economic evaluation is doneschematically enterprise technical and economic evaluation. Based on the geologicalsurvey work, and analog vicinity shale gas exploration technical indicators. Theschematically technical and economic evaluation multi-uses Static Evaluation. Themain evaluation indicators is total profits, static investment yield, static investmentpayback period and so on. In order to achieve the results of the evaluation of scientificand reasonable. When using a static economic evaluation, several evaluation index above are used together, comprehensive evaluated in this evaluation.Finally, for a comprehensive evaluation of shale gas, consider that the Yangtzeregion with favorable prospects for shale gas accumulation and resource potential,andin its current technical conditions, will receive considerable economic benefits.
