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

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields. This thesis presents a comparative study of various EOR techniques to assess their effectiveness in improving oil recovery from mature reservoirs. The research methodology involved a comprehensive literature review to analyze the current state-of-the-art EOR technologies and their application in mature oil fields. The study focused on ten key EOR methods, including chemical flooding, gas injection, thermal methods, and microbial EOR, among others. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance of the study, structure of the thesis, and definition of key terms. Chapter 2 presents a detailed literature review of existing studies and advancements in EOR techniques for mature oil fields. The review highlights the principles, applications, advantages, and limitations of each EOR method, setting the foundation for the comparative analysis. In Chapter 3, the research methodology is described, including the selection criteria for the comparative study, data collection methods, analysis techniques, and simulation models used to evaluate the performance of EOR techniques. The chapter also discusses the challenges and considerations in conducting comparative assessments of EOR methods in mature oil fields. Chapter 4 presents the findings of the comparative study, analyzing the effectiveness of each EOR technique in terms of oil recovery efficiency, production rates, cost implications, and environmental impact. The discussion delves into the technical feasibility, operational challenges, and reservoir-specific factors influencing the performance of EOR methods in mature oil fields. Finally, Chapter 5 offers a comprehensive conclusion and summary of the thesis, highlighting the key findings, implications for the industry, and recommendations for future research. The study underscores the importance of selecting the most suitable EOR technique based on reservoir characteristics, economic viability, and environmental considerations to optimize oil recovery from mature oil fields. In conclusion, this thesis contributes to the ongoing research in EOR technologies by providing a comparative analysis of techniques tailored for mature oil fields. The insights gained from this study can aid petroleum engineers, reservoir managers, and decision-makers in selecting the most effective EOR strategies to enhance oil production from mature reservoirs while addressing economic and environmental challenges.
