Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to investigate and evaluate various advanced techniques that can be employed to enhance oil recovery in mature oil fields. Mature oil fields are those that have been in production for an extended period of time and have experienced a decline in oil production rates. By implementing enhanced oil recovery (EOR) techniques, it is possible to extract more oil from these mature fields, thereby maximizing the economic benefits and extending the life of the reservoir. The research will begin with a comprehensive literature review to explore the existing knowledge and latest developments in EOR techniques specifically tailored for mature oil fields. This will include assessing various methods such as thermal, chemical, and gas injection techniques, as well as emerging technologies like nanotechnology and microbial enhanced oil recovery. The methodology chapter will outline the approach taken to conduct the research, including data collection methods, experimental procedures, and simulation techniques used to analyze the effectiveness of different EOR techniques. This will involve field studies, laboratory experiments, and computer simulations to determine the most suitable methods for enhancing oil recovery in mature fields. The findings chapter will present the results of the research, including the performance of different EOR techniques in terms of oil recovery efficiency, cost-effectiveness, and environmental impact. The discussion will delve into the implications of the findings, highlighting the key factors that influence the success of EOR projects in mature oil fields. In conclusion, the research will summarize the key findings and recommendations for the successful implementation of enhanced oil recovery techniques in mature oil fields. By leveraging advanced technologies and innovative approaches, it is possible to unlock the untapped potential of mature oil fields and sustainably increase oil production rates for years to come.
