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

Thesis Abstract

Abstract
This thesis investigates the application of enhanced oil recovery (EOR) techniques in mature oil fields, focusing on a comparative study to evaluate the effectiveness of various methods in maximizing oil production. The study addresses the challenges faced by mature oil fields in maintaining production levels and explores how different EOR techniques can help extend the economic life of these fields. The research begins with an introduction that sets the context for the study, highlighting the importance of EOR in the petroleum industry. It then delves into the background of the study, providing an overview of mature oil fields and the significance of implementing EOR strategies in such reservoirs. The problem statement identifies the declining production rates in mature fields as a key challenge, prompting the need for innovative EOR solutions. The objectives of the study are to compare and analyze different EOR techniques, assess their applicability in mature oil fields, and determine their impact on oil recovery rates. The limitations of the study are acknowledged, including data availability, field-specific constraints, and technical complexities. The scope of the study outlines the geographical and technical boundaries within which the research will be conducted. The significance of the study lies in its potential to contribute valuable insights to the petroleum industry, offering guidance on selecting the most suitable EOR methods for mature oil fields. The structure of the thesis is detailed, providing a roadmap of the chapters and sub-sections that will be explored in the research work. Definitions of key terms are also provided to ensure clarity and understanding of the concepts discussed. The literature review in Chapter Two presents a comprehensive analysis of existing studies and research findings related to EOR techniques in mature oil fields. Ten key items are covered, including the principles of EOR, reservoir characteristics, fluid properties, and economic considerations. The review serves as a foundation for understanding the current state of knowledge in the field and identifying gaps for further investigation. Chapter Three focuses on the research methodology, outlining the approach, data collection methods, simulation techniques, and analytical tools that will be used in the study. Eight contents are discussed, including field case studies, numerical modeling, and laboratory experiments, to provide a robust framework for conducting the comparative analysis. Chapter Four presents a detailed discussion of the findings, comparing the performance of different EOR techniques in mature oil fields. The analysis includes data interpretation, simulation results, and economic evaluations to assess the effectiveness of each method in enhancing oil recovery rates. The chapter offers insights into the practical applications and limitations of the various EOR techniques studied. Finally, Chapter Five concludes the thesis by summarizing the key findings, highlighting the implications for the petroleum industry, and providing recommendations for future research and field applications. The conclusion encapsulates the significance of the study and its contributions to advancing knowledge in EOR practices for mature oil fields.
