These weak formations\u0000may not detain sand particle movement, and produce along with the hydrocarbon fluids at high rates. This undesirable\u0000sand production can cause many different problems at surface as well as at sub-surface. An effective way of dealing\u0000with this problem is the use of gravel pack technique. However, designing gravel pack treatment requires consideration\u0000of different influencing parameters. This research aims to study the performance of gravel pack along with the gravel\u0000pack height and permeability on the well flow. The approach taken in this study includes the well performance\u0000modeling using a commercial simulator. A filed data is collected for gas condensate well that is being produced from\u0000Lower Goru Massive Sand Formation. The collected field data is simulated to compare the performance of Gas\u0000Condensate well before and after gravel pack completion. With this, the analysis is carried out to determine the effect\u0000of gravel pack height 8 permeability on flow parameters (i.e; flow rates of fluids, sand control losses, frictional losses,\u0000sand control skin, gravel pack critical velocity). Lastly, an appropriate height and permeable gravel is recommended\u0000on the basis of simulation results.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128380670","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}

Cement\u0000isolates the wellbore in completion of oil and gas wells, prevents failure of casing, and it also prevents wellbore fluids\u0000so that they cannot be contaminated from fresh water aquifers. In slurry state cement is distinguished by rheological\u0000properties like plastic viscosity and yield stress. Proper selection of cement slurries plays a vital role in well\u0000commenting and that could be possible with the utilization of efficient materials that may results the superior\u0000rheological properties of cement slurry i.e. plastic viscosity, gel and yield strength. The selection of cement has been\u0000done on account of higher values of compressive strengths for which quality of cement sheath will be enhanced.\u0000Cement Slurry design can be optimized by operators for which it is mandatory for operators that they have\u0000knowledge about actual temperature that cement will encounter inside wellbore. Down hole temperatures of\u0000cementing have impact on thickening time, rheology, and compressive strength development. In this research work\u0000Rice Husk Ash (RHA) and Egg Shell Powder (ESP) are used in cement slurry so that compressive strength of cement\u0000specimen can be increased. The cement slurry has been made from locally manufactured cement, water, RHA and\u0000ESP. Cement slurry of 600ml by volume has been prepared. Specimens with size of 2×2×2 inch cubic molds are made\u0000for compressive strength testing at different curing conditions. Three variants of the specimen with varying\u0000concentrations of RHA and ESP are made. In present work during slurry state the rheological properties are\u0000determined while in solid state compressive strength of cement specimen at three curing ages of 08 hours, 24 hours\u0000and 72 hours is determined.","PeriodicalId":192480,"journal":{"name":"International Journal of Current Engineering and Technology","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130833125","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}
