Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
The oil and gas industry plays a crucial role in the global economy, and the challenge of maximizing oil recovery from mature oil fields has become increasingly important. Enhanced oil recovery (EOR) techniques offer innovative solutions to increase oil production and extend the economic life of mature fields. This thesis investigates various EOR techniques and their application in mature oil fields to optimize production and maximize recovery rates. Chapter 1 provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. The introduction sets the stage for the study by highlighting the importance of EOR techniques in addressing the challenges of mature oil fields. Chapter 2 presents a comprehensive literature review of EOR techniques, including thermal methods such as steam injection and in-situ combustion, chemical methods like polymer flooding and surfactant flooding, and gas injection methods such as carbon dioxide and nitrogen injection. The review examines the principles, advantages, and limitations of each technique, highlighting successful applications in mature oil fields worldwide. Chapter 3 outlines the research methodology employed in the study, including the selection of case studies, data collection methods, analysis techniques, and simulation models used to assess the performance of EOR techniques in mature oil fields. The chapter also discusses the criteria used to evaluate the effectiveness and feasibility of different EOR methods in enhancing oil recovery. Chapter 4 presents a detailed discussion of the findings from the case studies and simulations, analyzing the impact of EOR techniques on oil recovery, production rates, and economic viability in mature oil fields. The chapter explores the synergies and trade-offs between different EOR methods, identifying key factors that influence their success and applicability in specific reservoir conditions. Chapter 5 concludes the thesis by summarizing the key findings, implications, and recommendations for future research and field applications. The conclusion highlights the importance of implementing integrated EOR strategies tailored to the unique characteristics of mature oil fields to achieve sustainable production and economic benefits. In conclusion, this thesis provides a comprehensive analysis of EOR techniques for mature oil fields, offering insights into the challenges, opportunities, and best practices for enhancing oil recovery and maximizing production efficiency. The research contributes to the existing body of knowledge in petroleum engineering and offers practical guidance for oil and gas operators seeking to optimize the performance of mature oil fields through advanced EOR technologies.
