Thesis Overview

The project "Optimization of Enhanced Oil Recovery Techniques in Mature Oilfields" aims to address the challenges faced in maximizing oil production from mature oilfields through the implementation of advanced Enhanced Oil Recovery (EOR) techniques. Mature oilfields are characterized by declining production rates and increased water cut, making it crucial to optimize recovery methods to extract the remaining oil efficiently. This research project focuses on evaluating and improving existing EOR techniques such as water flooding, gas injection, chemical flooding, and thermal methods in the context of mature oilfields. The research will begin with a comprehensive review of literature on EOR techniques, focusing on their applications in mature oilfields and their effectiveness in enhancing oil recovery rates. By analyzing past studies and industry practices, the project aims to identify the most promising EOR methods for mature oilfields and potential areas for optimization. The methodology chapter will outline the research approach, including data collection methods, experimental design, and simulation techniques. Field studies and laboratory experiments will be conducted to assess the performance of various EOR techniques in mature oilfields, considering factors such as reservoir characteristics, fluid properties, and operational constraints. The findings chapter will present the results of the research, including comparative analyses of different EOR techniques, simulation models, and field trial outcomes. The discussion will focus on the effectiveness of each method in maximizing oil recovery, addressing challenges, and proposing recommendations for optimization. In conclusion, the study will provide valuable insights into the optimization of EOR techniques in mature oilfields, offering practical recommendations for industry stakeholders to enhance production rates, extend field life, and maximize economic returns. By advancing knowledge in this critical area of petroleum engineering, the research aims to contribute to sustainable energy practices and the efficient utilization of existing oil reserves."
