Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oilfields: A Case Study" focuses on exploring innovative methods to revitalize mature oilfields and maximize oil production. Mature oilfields are those that have been in operation for a significant period and have experienced a decline in production rates. The challenge with mature oilfields lies in the fact that conventional oil recovery methods may no longer be as effective in extracting the remaining oil reserves. This research aims to investigate and implement enhanced oil recovery (EOR) techniques tailored to the specific characteristics of mature oilfields to increase the overall oil production. The study begins with a comprehensive literature review to analyze existing EOR techniques and their applications in mature oilfields. By examining successful case studies and industry practices, the research aims to identify the most promising EOR methods for enhancing oil recovery in mature fields. This review will provide a solid foundation for understanding the current state-of-the-art in EOR technologies and their potential benefits for mature oilfield operations. The research methodology involves conducting a detailed analysis of a selected mature oilfield as a case study. By leveraging field data, reservoir simulations, and economic evaluations, the project aims to assess the feasibility and effectiveness of implementing specific EOR techniques in the chosen field. The methodology will also involve numerical modeling and simulation studies to predict the performance of different EOR methods under varying reservoir conditions. The findings and discussion chapter will present the results of the case study analysis, highlighting the impact of different EOR techniques on oil recovery rates, production costs, and overall field performance. The discussion will delve into the technical and economic considerations of implementing EOR methods in mature oilfields, providing insights into the challenges and opportunities associated with each approach. In conclusion, this research aims to provide valuable insights into the application of enhanced oil recovery techniques in mature oilfields, offering practical recommendations for optimizing oil production and extending the economic life of aging fields. By addressing the unique challenges faced by mature oilfields and identifying tailored EOR solutions, this study seeks to contribute to the sustainable development of oil reserves and the enhancement of energy security in the oil and gas industry.
