Thesis Overview

The project "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to investigate and analyze innovative methods and technologies that can be employed to increase oil recovery from mature oil fields. As oil fields age, their production naturally declines, leading to decreased profitability and resource depletion. Enhanced oil recovery (EOR) techniques offer the potential to revitalize mature oil fields by maximizing the extraction of remaining oil reserves. The research will begin with a comprehensive literature review to explore existing EOR techniques and their applications in mature oil fields. This will provide a solid foundation for understanding the current state of the industry and identifying gaps where improvements can be made. Special attention will be given to evaluating the effectiveness, cost-efficiency, and environmental impact of different EOR methods. The project will then focus on developing a research methodology to investigate the feasibility and performance of selected EOR techniques in a real-world setting. This will involve conducting field studies, laboratory experiments, and simulation modeling to assess the efficacy of various EOR strategies under different reservoir conditions. The findings of the research will be presented and discussed in detail, highlighting the key insights, challenges, and opportunities identified during the study. The discussion will also address the practical implications of implementing EOR techniques in mature oil fields, including potential barriers and risks that need to be considered. In conclusion, this research project aims to contribute valuable insights and recommendations for the oil and gas industry on how to optimize oil recovery from mature fields using advanced EOR techniques. By enhancing the understanding of EOR technologies and their applications, this study seeks to promote sustainable energy practices and maximize the utilization of oil resources for future generations.
