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

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques are essential for maximizing hydrocarbon production from mature oil fields. This comparative study evaluates various EOR methods to determine their effectiveness in enhancing oil recovery from mature oil fields. The research focuses on comparing the performance of primary, secondary, and tertiary recovery methods, including water flooding, gas injection, chemical flooding, and thermal methods. The study assesses the technical, economic, and environmental aspects of each EOR technique to provide insights into the most suitable approach for mature oil fields. Chapter One provides an introduction to the research topic, discussing the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter Two presents a comprehensive literature review on EOR techniques, highlighting the principles, applications, advantages, and limitations of each method. The review includes ten key aspects related to EOR in mature oil fields, such as reservoir characteristics, fluid properties, and operational challenges. Chapter Three outlines the research methodology, detailing the approach, data collection methods, data analysis techniques, experimental setup, and simulation models used in the study. The chapter includes eight main sections covering the experimental design, laboratory testing procedures, numerical simulations, and data interpretation methods employed to evaluate the performance of EOR techniques in mature oil fields. Chapter Four presents a detailed discussion of the research findings, comparing the effectiveness of different EOR methods based on their ability to increase oil recovery rates, improve sweep efficiency, and reduce production costs in mature oil fields. The chapter analyzes the technical feasibility, economic viability, and environmental impact of each EOR technique to identify the optimal solution for maximizing hydrocarbon production from mature reservoirs. Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research results, and providing recommendations for future studies in the field of EOR for mature oil fields. The conclusion highlights the importance of selecting the most suitable EOR method based on reservoir conditions, fluid properties, and operational constraints to achieve sustainable oil production and maximize resource recovery from mature oil fields. Overall, this comparative study contributes to the existing knowledge on EOR techniques for mature oil fields by providing a comprehensive analysis of various methods and their applicability in enhancing oil recovery rates. The research outcomes offer valuable insights for petroleum engineers, reservoir managers, and decision-makers in the oil and gas industry to optimize production strategies and extend the economic lifespan of mature oil fields.
