Thesis Overview

The project titled "Optimizing Enhanced Oil Recovery Techniques for Mature Oilfields" aims to address the pressing need for maximizing oil production from mature oilfields through the utilization of advanced enhanced oil recovery (EOR) techniques. Mature oilfields are characterized by declining production rates and significant amounts of remaining oil reserves that are challenging to extract using conventional methods. This research project seeks to investigate and optimize the application of EOR techniques tailored specifically for mature oilfields to enhance oil recovery efficiency and extend the economic viability of these assets. The research will begin with a comprehensive review of the current state of EOR technologies and their applications in mature oilfields. This literature review will explore the various EOR methods available, such as chemical flooding, gas injection, and thermal methods, highlighting their advantages, limitations, and successful case studies in mature oilfield settings. By synthesizing existing knowledge and identifying gaps in research, the study aims to provide a solid foundation for the subsequent investigation. The research methodology will involve a combination of theoretical modeling, laboratory experiments, and field-scale simulations to assess the effectiveness of different EOR techniques in mature oilfield conditions. Special emphasis will be placed on developing innovative strategies to overcome the challenges associated with reservoir heterogeneity, fluid properties, and operational constraints that are common in mature oilfields. By leveraging advanced reservoir characterization techniques and simulation tools, the project aims to optimize the design and implementation of EOR processes to achieve maximum oil recovery. The findings of the study will be presented in a detailed discussion, highlighting the key insights, successes, and areas for further improvement in optimizing EOR techniques for mature oilfields. The analysis will include comparisons of different EOR methods, their economic feasibility, environmental impacts, and operational considerations to provide practical recommendations for industry stakeholders and decision-makers. In conclusion, the research project on "Optimizing Enhanced Oil Recovery Techniques for Mature Oilfields" holds significant potential to contribute to the sustainable development of oil and gas resources by unlocking the untapped reserves in mature oilfields. By advancing our understanding of EOR technologies and their applications in mature reservoirs, this study aims to offer valuable insights that can inform future strategies for maximizing oil recovery and prolonging the productive life of mature oilfields."
