Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Analysis

Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a vital role in maximizing hydrocarbon extraction from mature oilfields, which are characterized by declining production rates and significant remaining oil reserves. This thesis presents a comprehensive comparative analysis of various EOR techniques to evaluate their effectiveness in mature oilfields. The study focuses on understanding the key challenges faced in mature oilfields and the potential solutions offered by different EOR methods. Through an in-depth literature review, the research examines the principles, applications, and success factors of EOR techniques, including chemical, thermal, and miscible methods. The first chapter 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. The subsequent chapter conducts a detailed literature review, analyzing ten key studies related to EOR techniques in mature oilfields. This section explores the theoretical foundations, practical applications, and comparative advantages of different EOR methods. Chapter three outlines the research methodology employed in this study, encompassing eight key components such as data collection methods, research design, sampling techniques, and data analysis procedures. The methodology aims to provide a systematic framework for evaluating and comparing the performance of EOR techniques in mature oilfields. Chapter four presents a thorough discussion of the research findings, focusing on the comparative analysis of EOR techniques based on their efficiency, cost-effectiveness, environmental impact, and adaptability to various reservoir conditions. This section critically evaluates the strengths and limitations of each EOR method and identifies best practices for optimizing hydrocarbon recovery in mature oilfields. Finally, chapter five offers a conclusive summary of the research findings, highlighting the key insights, implications, and recommendations derived from the comparative analysis of EOR techniques for mature oilfields. The conclusion underscores the importance of adopting integrated EOR strategies to enhance oil recovery efficiency and sustainability in mature oilfields. In conclusion, this thesis contributes to the existing body of knowledge on EOR techniques by providing a comprehensive comparative analysis tailored to the specific challenges and opportunities presented by mature oilfields. The findings offer valuable insights for petroleum engineers, reservoir managers, and decision-makers seeking to optimize hydrocarbon extraction and extend the productive lifespan of mature oilfields through the strategic application of EOR methods.
