Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a crucial role in maximizing the production of mature oil fields, which represent a significant portion of global oil reserves. This thesis focuses on investigating and evaluating various EOR methods to enhance the recovery of oil from mature oil fields. The study begins with a comprehensive literature review of existing EOR techniques, including water flooding, gas injection, chemical flooding, and thermal methods. The research methodology involves field case studies, laboratory experiments, and simulation studies to assess the effectiveness of different EOR methods in mature oil fields. Chapter Four presents a detailed discussion of the findings, analyzing the performance of various EOR techniques in terms of oil recovery efficiency, cost-effectiveness, and environmental impact. The results indicate that each EOR method has its advantages and limitations, depending on the reservoir characteristics and field conditions. Water flooding is found to be the most commonly used EOR method due to its simplicity and cost-efficiency, but advanced techniques such as gas injection and chemical flooding show promising results in enhancing oil recovery rates. In conclusion, this thesis provides valuable insights into the application of EOR techniques for mature oil fields, highlighting the importance of selecting the most suitable method based on reservoir properties and economic considerations. The study contributes to the advancement of EOR technology and offers recommendations for optimizing oil recovery from mature oil fields to meet the growing global energy demand.
