The study evaluates the effectiveness of each technique in enhancing oil recovery rates and explores their applicability in different reservoir conditions. Additionally, the research methodology includes field case studies and simulation models to analyze the performance of EOR strategies in mature oil fields. The findings of the study highlight the potential benefits of implementing EOR techniques in mature oil reservoirs, such as increased oil production, improved ultimate recovery factors, and extended field life. The results also discuss the challenges and limitations associated with each EOR method, including technical complexities, cost considerations, and environmental concerns. Furthermore, the study provides insights into the optimal design and implementation of EOR projects to achieve sustainable oil recovery in mature fields. In conclusion, this thesis emphasizes the importance of utilizing advanced EOR techniques to enhance oil recovery from mature oil reservoirs. The research findings contribute to the existing knowledge base on EOR methods and provide valuable recommendations for oil industry professionals, reservoir engineers, and policymakers involved in maximizing hydrocarbon production from mature fields. The study underscores the significance of innovation and technology adoption in addressing the challenges of declining oil reserves and sustaining energy security in the global oil market.

Thesis Overview

The research project titled "Enhanced Oil Recovery Techniques for Mature Oil Reservoirs" aims to investigate and analyze advanced methods for increasing the recovery of oil from mature oil reservoirs. Mature oil reservoirs are those that have been in production for an extended period, and conventional recovery methods have already been employed to extract the majority of the available oil. This research seeks to explore innovative techniques that can enhance oil recovery efficiency in these mature reservoirs, ultimately extending the economic life of the field and maximizing oil production. The study will begin with a comprehensive literature review to examine existing enhanced oil recovery (EOR) techniques and technologies that have been successfully applied in mature oil reservoirs around the world. This review will provide a foundation for understanding the current state-of-the-art practices in the industry and identify gaps or areas for improvement in EOR applications for mature fields. Following the literature review, the research will delve into the methodology employed in the study. This will involve the selection and implementation of specific EOR techniques suitable for mature oil reservoirs, considering factors such as reservoir characteristics, fluid properties, and economic feasibility. The research methodology will also include simulation studies and laboratory experiments to evaluate the performance and effectiveness of the chosen EOR methods in enhancing oil recovery from mature reservoirs. The findings of the research will be presented and discussed in detail in the subsequent chapters, highlighting the key outcomes, insights, and implications of the study. The discussion will include an analysis of the benefits and challenges associated with the selected EOR techniques, as well as recommendations for optimizing their application in mature oil reservoirs. In conclusion, this research project on enhanced oil recovery techniques for mature oil reservoirs seeks to contribute to the advancement of EOR practices in the oil and gas industry. By exploring innovative methods and strategies for increasing oil recovery from mature fields, the study aims to provide valuable insights that can help operators and engineers maximize the production potential of existing reservoirs and extract additional reserves efficiently and sustainably.
