Thesis Overview

The project titled "Optimization of Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to address the critical challenge of maximizing oil production from mature oil fields through the application of advanced enhanced oil recovery (EOR) techniques. Mature oil fields are characterized by declining production rates and significant unrecovered reserves, making them prime candidates for EOR strategies to enhance oil recovery efficiency. The research will begin with a comprehensive literature review to explore existing EOR techniques, such as steam flooding, gas injection, chemical flooding, and microbial EOR, and their applications in mature oil fields. This review will provide a deep understanding of the current state-of-the-art technologies and their effectiveness in improving oil recovery from mature reservoirs. The methodology chapter will outline the research approach, including data collection, analysis, and simulation studies to evaluate the performance of different EOR techniques in mature oil fields. Advanced reservoir simulation tools will be utilized to model the reservoir characteristics, fluid properties, and production profiles to assess the impact of EOR methods on oil recovery rates and field economics. The findings chapter will present the results of the simulation studies, comparing the performance of various EOR techniques in terms of incremental oil recovery, production enhancement, and cost-effectiveness. The discussion will analyze the key factors influencing the success of EOR applications in mature oil fields, such as reservoir heterogeneity, fluid behavior, rock properties, and operational considerations. In conclusion, the research will provide valuable insights into the optimization of EOR techniques for mature oil fields, offering practical recommendations for industry stakeholders to enhance oil recovery efficiency, extend field life, and maximize economic returns. The project aims to contribute to the sustainable development of mature oil fields by leveraging innovative EOR solutions to unlock untapped reserves and achieve higher production levels in a cost-effective and environmentally responsible manner.
