Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields, where conventional recovery methods have reached their limits. This thesis focuses on investigating and analyzing various EOR techniques that can be applied to mature oil fields to enhance oil recovery efficiency. The study begins with a comprehensive review of the background and current state of mature oil fields, highlighting the challenges faced in extracting remaining oil reserves. The problem statement emphasizes the need for advanced recovery methods to optimize production levels and extend the economic viability of mature oil fields. The objectives of this study include identifying suitable EOR techniques for mature oil fields, evaluating their effectiveness, and providing recommendations for practical implementation. The limitations of the study are acknowledged, primarily concerning the availability of data and resources for conducting field tests and simulations. The scope of the study encompasses a thorough analysis of key EOR methods, including chemical, thermal, and gas injection techniques, with a focus on their application in mature oil fields. The significance of this study lies in its potential to contribute valuable insights to the oil and gas industry, assisting operators in maximizing oil recovery rates and prolonging the productive life of mature fields. The structure of the thesis is outlined, detailing the organization of chapters and the flow of content to address the research objectives systematically. Additionally, key terminologies relevant to EOR and mature oil fields are defined to establish a common understanding for readers. The literature review chapter provides a detailed analysis of ten key EOR techniques, exploring their principles, advantages, and limitations in the context of mature oil fields. Chapter three outlines the research methodology, including data collection methods, analytical tools, and simulation techniques used to evaluate EOR performance in mature oil fields. The discussion of findings in chapter four presents a comprehensive analysis of the effectiveness of selected EOR techniques, highlighting key factors influencing their success and potential challenges in implementation. In conclusion, this thesis offers valuable insights into the application of enhanced oil recovery techniques for mature oil fields, emphasizing the importance of adopting innovative strategies to optimize hydrocarbon production. The summary highlights the key findings and recommendations derived from the study, providing actionable insights for industry practitioners and researchers seeking to enhance oil recovery efficiency in mature fields. Overall, this research contributes to the ongoing efforts to sustainably exploit oil resources and address the challenges associated with mature oil field development.
