The horizontal well with multistage hydraulic fracturing has proven to be an effective operation of development these unconventional reservoirs. Most of modeling effort has been made for earlier liner flow. A simple analytical model for long-term shale gas production evaluation is still lacking. This work fill this gap. A simple and accurate mathematical model are developed which considering linear flow in both shale matrix and fracture. It can describe the longterm shale gas production with pseudo steady state flow. The model is verified against a Fayetteville field case data. The difference between the production rate given by the model and measured data was found to be less than 10%. The effect of fracture geometry parameter on long-term production rate are also investigated. The results show the fracture spacing and fracture length is the most dominant factors on thelong-term shale gas production performance.This model provides reservoir engineers a simple and accurate tool for predicting, evaluating and optimizing the long-term performance of shale gas wells.","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":"76 1","pages":"06-15"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84056623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has embolden many investigations on the determination of wind loads on different structures. Usually the estimation of wind loads in Buildings is carried out using codes and standards, whose enumeration are generally based on wind tunnel tests performed on selected building structures with common shapes. For example in India, A draft code of IS-875 (Part 3) for wind loading gives specifications for rectangular square, cylindrical and some typical Industrial Structures. Wind pressure estimation in buildings having shapes different from that specified on codes and standard requires wind tunnel studies. Also, Wind tunnel studies are expensive in terms of resources and time. The project suggests the Dynamic analysis for determination of wind pressure (loads) in buildings and structures. MS Excel is commanding enough for the calculation of wind pressure distribution to more cases than those currently covered by limited wind tunnel data. Some comparisons were also done using STAAD Pro with the dynamic response of building considering some examples. MS Excel has been used to determine the along wind and across wind response of a tall building. A draft code CED-37 (7792) was used to generate data for the along and across wind response of a tall building by varying various parameters as height, width, depth, terrain category, basic wind speed and force coefficient for the building. Finally, calculation of response of along and across wind of any dimension of building can be done with the draft code provisions and necessity of that is discussed","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":"29 1","pages":"71-76"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82805913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These days manufacturing is also viewed from broader perspective of sustainability, therefore, manufacturing companies are also pushing them to achieve various dimensions of sustainability, such as social, economical and environmental. Industries are regularly working on reducing their carbon footprint. Energy management is one of the method through which industries are focusing on reduction of carbon footprint and cost to become more sustainable in this competitive time. Regular cost reduction pressure on auto component manufacturing company from their Original Equipment Manufacturer (OEM) is increasing day by day due to competition in market. To compensate the pressure auto-component manufacturing industries are taking many initiatives. Apart from raw material and manpower cost, energy cost is also one of the major contributors. Due to carbon footprint the role of energy management has greatly expanded. Major industries are contracting with energy service providers to implement energy management practices to improve efficiency. The present study aims to identify the energy management practices adopted by an auto ancillary to reduce its carbon footprint for environmentally sustainable manufacturing.","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":"23 1","pages":"20-25"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87117757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
