Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study

Thesis Abstract

Abstract
This thesis investigates Enhanced Oil Recovery (EOR) techniques for mature oil fields through a comparative study to enhance the understanding of optimal strategies for maximizing oil extraction. The oil industry is facing challenges in maintaining production levels from mature oil fields due to declining reservoir pressure and the exhaustion of primary recovery methods. EOR methods offer promising solutions to improve oil recovery rates and extend the economic life of mature fields. This study focuses on comparing different EOR techniques to identify the most effective approach for enhancing oil recovery in mature fields. The research begins with an introduction that provides background information on the significance of EOR in the oil industry and the specific challenges faced by mature oil fields. The problem statement highlights the need for improved recovery methods to extract remaining oil reserves efficiently. The objectives of the study are outlined to investigate and compare various EOR techniques, analyze their effectiveness, and provide recommendations for practical applications. The literature review section explores existing studies on EOR techniques, including thermal methods, gas injection, chemical flooding, and microbial EOR. The review of literature aims to establish a comprehensive understanding of the benefits and limitations of each technique, as well as their application in mature oil fields. The methodology chapter outlines the research design, data collection methods, and analysis techniques used to compare EOR techniques based on performance indicators such as oil recovery efficiency, cost-effectiveness, and environmental impact. The findings chapter presents a detailed analysis of the comparative study results, highlighting the performance of different EOR techniques in terms of oil recovery rates, production costs, and reservoir characteristics. The discussion delves into the implications of the findings and provides insights into the optimal EOR strategies for mature oil fields. Recommendations for industry practitioners and future research directions are also discussed to guide the implementation of EOR techniques in real-world applications. In conclusion, this thesis offers valuable insights into the selection and implementation of EOR techniques for enhancing oil recovery in mature fields. The comparative study sheds light on the strengths and weaknesses of different EOR methods, providing a framework for decision-making in the oil industry. By optimizing EOR strategies, operators can maximize oil production, increase profitability, and ensure the sustainable utilization of remaining oil reserves in mature fields.
