Project Overview

The project titled "Optimization of Enhanced Oil Recovery Techniques for Mature Oilfields" aims to address the challenge of declining oil production in mature oilfields by investigating and optimizing enhanced oil recovery (EOR) techniques. Mature oilfields are characterized by declining production rates due to the depletion of easily recoverable oil reserves. To maximize oil recovery and extend the economic viability of mature oilfields, the implementation of advanced EOR techniques is essential. The research will begin with a comprehensive literature review to provide a background on the existing EOR techniques and their applications in mature oilfields. Various EOR methods such as water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR will be explored to understand their effectiveness in enhancing oil recovery in mature reservoirs. The review will also analyze case studies and best practices in the industry to identify successful approaches and potential areas for improvement. The methodology chapter will outline the research approach, including data collection, analysis techniques, and simulation studies. Field experiments and laboratory tests may be conducted to evaluate the performance of different EOR techniques in a controlled environment before implementation in the field. The research will also involve reservoir modeling and simulation to optimize the design and implementation of EOR projects in mature oilfields. Chapter four will present a detailed discussion of the research findings, including the effectiveness of various EOR techniques in enhancing oil recovery, economic considerations, environmental impacts, and operational challenges. The analysis will highlight the key factors influencing the success of EOR projects in mature oilfields and provide recommendations for optimizing recovery rates and minimizing costs. In conclusion, the research will summarize the key findings and contributions to the field of petroleum engineering. The study aims to provide valuable insights into the optimization of EOR techniques for mature oilfields, offering practical recommendations for industry stakeholders to enhance oil recovery, extend field life, and maximize economic returns. By addressing the challenges of declining production in mature oilfields through advanced EOR strategies, this research seeks to contribute to sustainable energy development and resource management in the oil and gas industry.
