Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques are essential for maximizing oil production from mature oilfields. One of the promising methods for EOR is chemical injection, which involves the use of chemicals to improve the displacement efficiency of oil in reservoirs. This thesis focuses on investigating and evaluating the effectiveness of chemical injection for enhancing oil recovery in mature oilfields. The study aims to provide valuable insights into the application of chemical injection techniques and their impact on oil production. Chapter One provides an introduction to the research topic, presenting the background of the study, problem statement, objectives, limitations, scope, significance, and the structure of the thesis. The chapter also includes definitions of key terms to establish a clear understanding of the research context. Chapter Two presents a comprehensive literature review on enhanced oil recovery techniques, with a specific focus on chemical injection methods. The review covers the principles, mechanisms, and applications of chemical injection in mature oilfields, as well as recent advancements and case studies in the field. Chapter Three outlines the research methodology employed in this study. It includes the research design, data collection methods, sampling techniques, experimental procedures, and data analysis approaches. The chapter also discusses the theoretical framework guiding the research process. Chapter Four presents a detailed discussion of the findings obtained from the research. It includes the analysis of data collected through experiments, simulations, and case studies to evaluate the performance of chemical injection techniques in enhancing oil recovery in mature oilfields. The chapter also discusses the key factors influencing the effectiveness of chemical injection methods. Chapter Five serves as the conclusion and summary of the thesis. It provides a recap of the research objectives, key findings, implications of the study, and recommendations for future research. The chapter concludes with a discussion of the significance of the research in advancing the field of enhanced oil recovery through chemical injection. Overall, this thesis contributes to the understanding of enhanced oil recovery techniques for mature oilfields using chemical injection. The findings of this study can inform industry practices and decision-making processes to optimize oil production and reservoir performance in mature oilfields.
