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

Thesis Abstract

Abstract
This thesis presents a comprehensive study on Enhanced Oil Recovery (EOR) techniques applied to mature oil fields, focusing on comparing different methods to improve oil extraction efficiency and maximize production. The research investigates the challenges faced in mature oil fields, explores various EOR strategies, and evaluates their effectiveness in enhancing oil recovery rates. The study aims to provide valuable insights for the petroleum industry to optimize production from mature oil fields and extend their economic viability. The introduction section establishes the background of the study, highlighting the importance of EOR in the context of mature oil fields. It identifies the problem statement related to declining production rates and the need for innovative techniques to revitalize mature fields. The objectives of the study are outlined to analyze and compare different EOR methods, while also considering the limitations and scope of the research. The significance of the study is emphasized in addressing key industry challenges and contributing to sustainable oil production practices. Chapter two presents a detailed literature review comprising ten key items that explore existing research and case studies on EOR techniques for mature oil fields. The literature review provides a foundation for understanding the principles, applications, and outcomes of various EOR methods, including thermal, chemical, and gas injection techniques. By synthesizing prior studies, this chapter sets the stage for the subsequent analysis and discussion of findings. Chapter three outlines the research methodology employed in this study, encompassing eight essential components such as data collection methods, analytical tools utilized, and the criteria for selecting case studies. The methodology section describes how the comparative analysis of EOR techniques was conducted, ensuring a systematic approach to evaluating and interpreting the results. This chapter elucidates the rigorous process followed to achieve reliable and meaningful findings. Chapter four presents an in-depth discussion of the research findings, comparing the performance of different EOR techniques in mature oil fields. The analysis delves into factors influencing the effectiveness of each method, such as reservoir characteristics, production costs, and environmental considerations. By critically examining the results, this chapter offers valuable insights into the practical implications of implementing specific EOR strategies to optimize oil recovery in mature fields. Chapter five concludes the thesis by summarizing the key findings, discussing their implications for the petroleum industry, and presenting recommendations for future research and field applications. The conclusion underscores the importance of adopting advanced EOR technologies to sustainably exploit mature oil fields and meet global energy demands. Overall, this thesis contributes to enhancing the understanding of EOR techniques for mature oil fields and offers valuable guidance for improving oil recovery practices in the industry.
