Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Analysis" aims to investigate and compare various enhanced oil recovery (EOR) techniques suitable for mature oilfields. Mature oilfields are characterized by declining production rates and increased water cut, making it challenging to extract the remaining oil efficiently. The study will focus on identifying and evaluating EOR methods that can rejuvenate production in these mature oilfields. The research will commence with a comprehensive literature review to explore the existing EOR techniques and their applications in mature oilfields. This review will provide a solid foundation for understanding the principles, advantages, and limitations of each EOR method. The comparative analysis will involve assessing the technical feasibility, economic viability, and environmental implications of different EOR techniques in the context of mature oilfields. The methodology will involve data collection from case studies, simulation models, and field experiments to analyze the performance of selected EOR methods in mature oilfields. Factors such as reservoir characteristics, fluid properties, operational challenges, and cost-effectiveness will be considered to determine the most suitable EOR technique for each specific scenario. Advanced reservoir engineering tools and simulation software will be utilized to predict the reservoir behavior and optimize EOR strategies. The findings of this research will provide valuable insights into the effectiveness of various EOR techniques in enhancing oil recovery from mature oilfields. The comparative analysis will highlight the strengths and weaknesses of each method and offer recommendations for optimizing EOR processes in mature reservoirs. The results of this study are expected to contribute to the advancement of EOR practices and help operators make informed decisions to maximize oil production and extend the life of mature oilfields. In conclusion, the comparative analysis of EOR techniques for mature oilfields is a crucial research endeavor that addresses the challenges of declining production and resource depletion in aging reservoirs. By evaluating and comparing different EOR methods, this study aims to provide practical guidance for enhancing oil recovery efficiency and sustainability in mature oilfields, ultimately benefiting the oil and gas industry and ensuring the long-term productivity of existing oil reserves.
