Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study

Thesis Abstract

Abstract
This thesis investigates Enhanced Oil Recovery (EOR) techniques for mature oil fields through a comparative study aimed at improving oil production efficiency and maximizing recovery rates. The study focuses on analyzing and comparing various EOR methods to determine their effectiveness in revitalizing mature oil fields and increasing hydrocarbon extraction. The introduction provides a comprehensive overview of the background of the study, highlighting the challenges faced by the oil industry in exploiting remaining reserves in mature fields. The problem statement emphasizes the declining production rates in mature fields and the need for innovative EOR solutions to enhance recovery. The objectives of the study include evaluating different EOR techniques, identifying the most suitable method for mature fields, and assessing the economic viability of implementation. A thorough literature review in Chapter Two discusses ten key EOR methods, such as chemical flooding, gas injection, and thermal recovery, examining their principles, applications, advantages, and limitations in mature oil fields. This review serves as a foundation for understanding the existing knowledge and gaps in EOR technologies for mature reservoirs. Chapter Three outlines the research methodology, including the selection criteria for case studies, data collection methods, simulation techniques, and economic evaluation models. The chapter also describes the analytical tools and software used to compare and analyze the performance of different EOR techniques in mature fields. The methodology section provides a detailed explanation of the experimental approach employed in this study, ensuring the reliability and validity of the results. Chapter Four presents a comprehensive discussion of the findings from the comparative study, evaluating the effectiveness of various EOR methods in terms of oil recovery efficiency and economic feasibility. The chapter analyzes the performance of each technique in different reservoir conditions and identifies the most suitable EOR method for maximizing hydrocarbon extraction in mature fields. Furthermore, the discussion delves into the challenges and opportunities associated with implementing EOR technologies in aging reservoirs. Finally, Chapter Five offers a conclusive summary of the research findings, emphasizing the significance of the study in advancing EOR strategies for mature oil fields. The conclusion highlights the key recommendations for industry practitioners and policymakers to enhance oil recovery rates and extend the productive life of mature reservoirs. Overall, this thesis contributes valuable insights into the optimization of EOR techniques for revitalizing mature oil fields and improving sustainable energy production.
