Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study" aims to investigate and compare different methods for enhancing oil recovery in mature oil fields. Mature oil fields are those that have been in production for an extended period and typically exhibit declining production rates due to the depletion of reservoir pressure and the migration of oil. As such, it is crucial to explore and implement advanced techniques to maximize the recovery of remaining oil reserves in these fields. The research will begin with an introduction that provides background information on the challenges faced in mature oil fields and the importance of enhancing oil recovery. The problem statement will clearly define the research gap, highlighting the need for improved recovery methods. The objectives of the study will outline the specific goals and aims to be achieved through the research, focusing on comparing the effectiveness of different enhanced oil recovery techniques. Limitations of the study will be acknowledged to provide a clear understanding of the constraints and boundaries within which the research will be conducted. The scope of the study will define the specific aspects of enhanced oil recovery techniques and mature oil fields that will be examined. The significance of the study will emphasize the potential impact of the research findings on the oil and gas industry, highlighting the importance of maximizing oil recovery from mature fields. The structure of the thesis will outline the organization of the research work, detailing the chapters and sub-topics that will be covered. Definitions of key terms will be provided to ensure clarity and understanding of terminology used throughout the research. Chapter two will consist of a comprehensive literature review, examining existing studies and research on enhanced oil recovery techniques for mature oil fields. This section will analyze and compare various methods such as water flooding, gas injection, chemical enhanced oil recovery, and thermal methods to identify their advantages and limitations. Chapter three will focus on the research methodology, detailing the approach and techniques employed to collect and analyze data. This chapter will include sections on research design, data collection methods, data analysis techniques, and the rationale behind the chosen methodology. Chapter four will present a detailed discussion of the research findings, comparing the effectiveness of different enhanced oil recovery techniques in mature oil fields. This section will analyze the results obtained from the study and draw conclusions based on the findings. Finally, chapter five will provide a conclusion and summary of the research, highlighting the key findings, implications, and recommendations for future research. This section will conclude the study by summarizing the main points and emphasizing the significance of the research in advancing knowledge and practices in the field of petroleum engineering.
