Thesis Overview

The project titled "Optimization of Enhanced Oil Recovery Techniques in Mature Oilfields" aims to address the critical challenge of maximizing oil production from mature oilfields through the application of advanced enhanced oil recovery (EOR) techniques. Mature oilfields are characterized by declining production rates and increasing operational challenges due to the depletion of reservoir pressure and the presence of residual oil trapped in the formation. To overcome these challenges, the project focuses on optimizing the application of EOR techniques, such as water flooding, gas injection, and chemical flooding, to enhance oil recovery efficiency and increase overall production yields. The research will begin with a comprehensive literature review to explore the existing knowledge and best practices in EOR techniques, particularly in the context of mature oilfields. This review will provide valuable insights into the various methods, technologies, and strategies employed in the industry to improve oil recovery rates and maximize reservoir performance. By synthesizing and analyzing the findings from previous studies, the project aims to identify key factors that influence the effectiveness of EOR techniques in mature oilfields and establish a solid foundation for the subsequent research phases. Next, the project will focus on developing a robust research methodology that includes field studies, laboratory experiments, numerical simulations, and data analysis techniques. By combining theoretical frameworks with practical applications, the research aims to evaluate the performance of different EOR methods under varying reservoir conditions and operational parameters. This comprehensive approach will enable the project to generate valuable insights into the optimal design, implementation, and monitoring of EOR techniques in mature oilfields to achieve maximum oil recovery efficiency. Furthermore, the project will involve the collection and analysis of field data from selected mature oilfields to assess the impact of EOR techniques on reservoir performance, production rates, and ultimate oil recovery. By conducting detailed field studies and performance evaluations, the research aims to validate the effectiveness of the proposed optimization strategies and identify potential areas for further improvement and innovation. Finally, the project will conclude with a thorough discussion of the research findings, implications, and recommendations for industry practitioners, policymakers, and researchers. The research overview aims to contribute valuable knowledge and insights to the field of petroleum engineering and enhance the understanding of EOR techniques in mature oilfields, ultimately supporting sustainable oil production and reservoir management practices.
