Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to explore and evaluate various advanced methods and technologies for enhancing oil recovery in mature oil fields. Mature oil fields, characterized by declining production rates and increasing water cut, present a significant challenge for the oil and gas industry. By implementing enhanced oil recovery (EOR) techniques, it is possible to maximize the extraction of remaining oil reserves and extend the economic lifespan of these fields. The research will begin with a comprehensive literature review to examine existing EOR techniques such as thermal methods (e.g., steam injection), chemical methods (e.g., surfactant injection), and gas injection methods (e.g., CO2 and nitrogen injection). The review will also cover case studies of successful EOR projects in mature oil fields around the world to identify best practices and lessons learned. Following the literature review, the research will focus on developing a methodology for evaluating the feasibility and effectiveness of different EOR techniques in specific mature oil fields. This will involve conducting reservoir simulations, economic analysis, and risk assessment to determine the most suitable EOR method for a given field based on factors such as reservoir characteristics, fluid properties, and economic considerations. The project will also investigate the environmental impact of EOR techniques, including issues such as greenhouse gas emissions, water usage, and induced seismicity. Sustainable and environmentally friendly EOR practices will be emphasized to ensure that oil recovery operations are conducted in a responsible manner. The findings of the research will be presented in a detailed discussion that highlights the key insights and recommendations for implementing EOR techniques in mature oil fields. The discussion will address challenges and opportunities associated with EOR applications, as well as potential areas for future research and development. In conclusion, the project on "Enhanced Oil Recovery Techniques for Mature Oil Fields" seeks to contribute to the advancement of EOR technologies and practices to optimize oil recovery from mature fields. By enhancing the understanding of EOR methods and their potential benefits, this research aims to support the sustainable development of oil and gas resources while maximizing production efficiency and profitability in mature oil fields.
