Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study" aims to explore and compare various enhanced oil recovery (EOR) techniques specifically tailored for mature oil fields. As oil reserves continue to deplete worldwide, the need for efficient recovery methods becomes increasingly crucial. Mature oil fields, characterized by declining production rates and higher operating costs, present a significant challenge for the oil and gas industry. Therefore, this research seeks to investigate and analyze different EOR techniques to optimize production and extend the life of mature oil fields. The study will begin with a comprehensive literature review to establish a solid theoretical foundation. This review will cover existing EOR methods such as steam injection, gas injection (CO2 and natural gas), chemical flooding, and microbial EOR. By examining case studies and research findings, the advantages, limitations, and applicability of each technique will be critically evaluated. Following the literature review, the research methodology will be outlined, detailing the approach to data collection, analysis, and comparison of EOR techniques. This will involve conducting simulations, laboratory experiments, and field studies to assess the effectiveness of different methods in enhancing oil recovery from mature fields. Factors such as reservoir characteristics, fluid properties, and economic considerations will be taken into account to provide a comprehensive evaluation. The findings of the study will be presented and discussed in Chapter Four, highlighting the performance of various EOR techniques in terms of incremental oil recovery, cost-effectiveness, and environmental impact. A comparative analysis will be conducted to identify the most suitable EOR method for different types of mature oil fields based on reservoir conditions and operational constraints. Finally, Chapter Five will present the conclusions drawn from the research, summarizing the key findings and recommendations for industry practitioners and policymakers. The study aims to contribute valuable insights to the field of petroleum engineering by offering guidance on selecting and implementing optimal EOR strategies for mature oil fields to maximize production and extend the economic life of oil reservoirs. Overall, this research project on "Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study" seeks to address the pressing need for innovative solutions to sustain oil production from mature fields and ensure the long-term viability of the oil and gas industry."
