Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Analysis

Thesis Abstract

Abstract
The oil and gas industry has been facing challenges in recent years due to the depletion of easily accessible reserves, leading to increased interest in enhancing oil recovery techniques for mature oilfields. This thesis presents a comparative analysis of various enhanced oil recovery (EOR) techniques to optimize production from mature oilfields. The study aims to evaluate the effectiveness, feasibility, and economic viability of different EOR methods in enhancing oil recovery from mature oilfields. Chapter One provides an introduction to the research topic, highlighting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter Two presents a comprehensive literature review that explores existing research and studies on EOR techniques, including water flooding, gas injection, chemical EOR methods, thermal methods, and emerging technologies. Chapter Three discusses the research methodology employed in this study, including the research design, data collection methods, sampling techniques, data analysis procedures, and quality assurance measures. The chapter also outlines the theoretical framework used to analyze and compare the different EOR techniques. Chapter Four presents a detailed discussion of the findings from the comparative analysis of EOR techniques for mature oilfields. The chapter evaluates the performance of each EOR method in terms of oil recovery efficiency, production enhancement, reservoir characteristics, operational challenges, and economic considerations. The findings provide valuable insights into the most effective EOR techniques for maximizing oil recovery from mature oilfields. Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research results, and providing recommendations for future research and practical applications. The study contributes to the existing body of knowledge on EOR techniques for mature oilfields and offers valuable insights for oil and gas operators, researchers, and policymakers in the industry. In conclusion, this thesis sheds light on the importance of implementing effective EOR techniques to optimize production from mature oilfields. By comparing and analyzing various EOR methods, this study aims to provide valuable information that can guide decision-making processes in the oil and gas sector, ultimately contributing to sustainable resource management and enhanced recovery of hydrocarbon reserves.
