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

Thesis Abstract

Abstract
The global demand for oil continues to rise, prompting the industry to explore innovative ways to maximize oil recovery from mature oil fields. This thesis presents a comprehensive study on enhanced oil recovery techniques for mature oil fields, focusing on a comparative analysis of various methods to identify the most effective strategies for improving oil production. The research is motivated by the need to enhance the recovery factor of mature oil fields, which typically have lower primary recovery rates due to depleted reservoir pressure and other factors. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The chapter sets the stage for the study by highlighting the importance of enhancing oil recovery in mature oil fields and the need for comparative analysis to identify the most suitable techniques. Chapter 2 consists of a detailed literature review that examines existing studies, theories, and practices related to enhanced oil recovery techniques in mature oil fields. The chapter covers ten key areas, including water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies, providing a comprehensive overview of the different approaches used in the industry. Chapter 3 discusses the research methodology employed in this study, outlining the research design, data collection methods, sampling techniques, data analysis procedures, and quality assurance measures. The chapter also addresses ethical considerations and limitations to ensure the validity and reliability of the research findings. Chapter 4 presents the findings of the comparative analysis of enhanced oil recovery techniques in mature oil fields. The chapter discusses the effectiveness of each method in improving oil recovery, considering factors such as recovery factor, cost-effectiveness, environmental impact, and operational challenges. The findings provide valuable insights into the strengths and limitations of each technique, guiding the selection of the most suitable approach for specific field conditions. Chapter 5 concludes the thesis by summarizing the key findings, discussing the implications for the industry, and providing recommendations for future research and practical applications. The study contributes to the existing body of knowledge on enhanced oil recovery in mature oil fields, offering valuable insights for oil companies, researchers, and policymakers seeking to optimize oil production and extend the life of mature oil fields. Overall, this thesis enhances understanding of enhanced oil recovery techniques for mature oil fields through a comparative study, highlighting the importance of selecting the most effective strategies to maximize oil production and achieve sustainable energy development goals.
