Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a crucial role in maximizing the extraction of hydrocarbons from mature oil fields. As conventional oil production declines, the application of advanced EOR methods becomes increasingly important in maintaining production levels and extending the economic life of oil fields. This thesis focuses on evaluating and analyzing various EOR techniques suitable for mature oil fields, with a specific emphasis on their effectiveness, challenges, and potential for implementation. The introduction section provides an overview of the significance of EOR in the petroleum industry, particularly in mature oil fields where primary and secondary recovery methods have reached their limits. The background of the study outlines the historical development of EOR techniques and their evolution over time. The problem statement highlights the need for enhanced recovery methods to increase oil production rates and ultimate recovery factors from mature oil fields. The objectives of the study are to assess the performance of different EOR techniques, identify key challenges and limitations, define the scope of the research, and determine the significance of implementing EOR strategies in mature oil fields. The limitations of the study are also discussed, acknowledging the complexities and uncertainties associated with EOR projects. The literature review chapter presents a comprehensive analysis of existing research and case studies related to EOR techniques for mature oil fields. The review covers ten key aspects, including the principles of EOR, types of EOR methods, reservoir characteristics affecting EOR performance, field case studies, and advancements in EOR technology. The research methodology chapter outlines the approach and methodology used to evaluate and compare EOR techniques. It includes detailed descriptions of data collection methods, simulation modeling, economic analysis, and risk assessment processes. The methodology section also addresses the selection criteria for case studies and the parameters used to assess EOR performance. The discussion of findings chapter presents a detailed analysis of the results obtained from evaluating different EOR techniques in mature oil fields. The findings include comparisons of recovery factors, production rates, economic viability, and environmental considerations for each EOR method. The chapter also discusses the challenges and opportunities associated with implementing EOR projects in real-world scenarios. The conclusion and summary chapter provide a comprehensive overview of the key findings, implications, and recommendations generated from the study. The conclusion highlights the most effective EOR techniques for mature oil fields, key success factors, and future research directions in the field of enhanced oil recovery. In conclusion, this thesis contributes to the understanding of EOR techniques for mature oil fields and provides valuable insights for oil and gas companies, researchers, and policymakers involved in maximizing hydrocarbon recovery from aging reservoirs. The findings and recommendations can help guide decision-making processes and strategic planning for successful implementation of EOR projects in mature oil fields.
