Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing oil production from mature oil fields. This thesis presents a comprehensive comparative study of various EOR techniques to determine their effectiveness in enhancing oil recovery from mature oil fields. The research focuses on evaluating the performance of primary, secondary, and tertiary recovery methods, including water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. Chapter One provides an introduction to the research topic, presenting the background of the study, problem statement, research objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter Two offers a detailed literature review covering ten key aspects related to EOR techniques and their applications in mature oil fields, highlighting the latest advancements and challenges in the field. Chapter Three outlines the research methodology, including the selection of study sites, data collection methods, experimental design, modeling approaches, simulation techniques, and analysis procedures. The chapter also discusses the criteria used for comparing the various EOR techniques and evaluating their performance in mature oil fields. Chapter Four presents a comprehensive discussion of the research findings, including the comparative analysis of different EOR techniques based on their efficiency, cost-effectiveness, environmental impact, and applicability to mature oil fields. The chapter explores the strengths and limitations of each method, providing insights into their potential for improving oil recovery rates and extending the productive life of mature oil fields. Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research results, and offering recommendations for future research and practical applications in the field of enhanced oil recovery for mature oil fields. The study contributes valuable insights to the field of petroleum engineering by providing a comparative analysis of EOR techniques and their effectiveness in maximizing oil production from mature oil fields. In conclusion, this thesis serves as a valuable resource for petroleum engineers, oil field operators, researchers, and policymakers seeking to enhance oil recovery rates and sustainable hydrocarbon production from mature oil fields using advanced EOR techniques. The findings of this study have the potential to drive innovation and optimization in the oil and gas industry, leading to improved economic returns and environmental sustainability in the extraction of hydrocarbon resources.
