Thesis Overview

The research project titled "Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Analysis" aims to investigate and compare various enhanced oil recovery (EOR) techniques that can be applied to mature oilfields to maximize oil production. Mature oilfields are those that have been in production for an extended period and typically exhibit declining production rates. By exploring different EOR methods and their effectiveness in mature oilfields, this study seeks to provide valuable insights for optimizing oil recovery and extending the economic life of these fields. The project will begin with a comprehensive review of existing literature on EOR techniques, including but not limited to methods such as water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. This literature review will serve as a foundation for understanding the principles, advantages, and limitations of each technique in the context of mature oilfields. Subsequently, the research methodology will be outlined, detailing the approach for data collection, analysis, and comparison of EOR techniques. The methodology will include considerations for selecting case studies of mature oilfields, evaluating reservoir characteristics, and assessing the technical and economic feasibility of implementing different EOR methods. The core of the study will involve a detailed discussion of findings, where the performance of various EOR techniques in mature oilfields will be systematically analyzed and compared. Factors such as oil recovery efficiency, production enhancement, cost-effectiveness, and environmental impact will be critically evaluated to identify the most suitable EOR approaches for different types of mature oilfields. In conclusion, the research will summarize key findings, implications, and recommendations for industry practitioners, policymakers, and researchers involved in the field of petroleum engineering. By offering a comparative analysis of EOR techniques for mature oilfields, this study aims to contribute to the advancement of sustainable oil production practices and the optimization of reservoir management strategies in the oil and gas industry.
