Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Study

Thesis Abstract

Abstract
This thesis presents a comprehensive study on the application of enhanced oil recovery (EOR) techniques in mature oilfields, aiming to compare and evaluate the effectiveness of various methods in optimizing oil production. The research investigates the challenges faced by mature oilfields, such as declining production rates and increasing operational costs, and explores how EOR techniques can address these issues. The study focuses on analyzing different EOR methods, including thermal, chemical, and gas injection techniques, to determine their suitability for mature oilfields based on factors such as reservoir characteristics, cost-effectiveness, and environmental impact. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, research objectives, limitations, scope, significance, structure of the thesis, and definition of terms. The chapter sets the foundation for the research and highlights the importance of investigating EOR techniques in mature oilfields. Chapter 2 presents a thorough literature review that examines existing studies and research on EOR techniques in mature oilfields. The chapter discusses ten key aspects related to EOR methods, including their applications, advantages, limitations, and case studies. By synthesizing the findings from previous research, this chapter forms the theoretical framework for the current study. Chapter 3 details the research methodology employed in this study, including data collection methods, experimental design, sampling techniques, data analysis procedures, and validation techniques. The chapter outlines eight key components of the research methodology, providing a transparent and systematic approach to conducting the comparative study on EOR techniques in mature oilfields. Chapter 4 offers an in-depth discussion of the findings derived from the comparative analysis of EOR techniques in mature oilfields. The chapter presents the results of the research, highlights the strengths and weaknesses of each EOR method, and discusses the implications of the findings for the oil and gas industry. By evaluating the effectiveness of different EOR techniques, this chapter contributes valuable insights to the field of petroleum engineering. Chapter 5 concludes the thesis by summarizing the key findings, discussing the implications of the research, and providing recommendations for future studies and practical applications. The chapter also reflects on the significance of the study in advancing knowledge on EOR techniques for mature oilfields and offers concluding remarks on the research outcomes. Overall, this thesis contributes to the understanding of EOR techniques in mature oilfields and provides valuable insights for industry practitioners, researchers, and policymakers seeking to enhance oil recovery and optimize production in aging oil reservoirs.
