Thesis Overview

The research project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to investigate and analyze innovative methods and technologies to optimize the recovery of oil from mature oil fields. As oil reservoirs age, the natural pressure that drives oil production decreases, leading to reduced production rates. Enhanced oil recovery (EOR) techniques offer a promising solution to increase the extraction of remaining oil reserves in these mature fields. The project will begin with a comprehensive review of existing literature on EOR techniques, focusing on methods such as water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies like nanotechnology and microbial EOR. This literature review will provide a solid foundation for understanding the principles, advantages, and limitations of various EOR techniques. Following the literature review, the research methodology will be outlined, detailing the approach to data collection, analysis, and experimentation. The methodology will include field studies, laboratory experiments, and simulation models to evaluate the effectiveness of different EOR techniques in mature oil fields. Factors such as reservoir characteristics, fluid properties, and economic considerations will be taken into account to assess the feasibility and applicability of each method. The findings from the research will be presented and discussed in detail in the subsequent chapter, highlighting the performance of different EOR techniques in enhancing oil recovery from mature fields. The discussion will analyze the results, identify key challenges and opportunities, and propose recommendations for optimizing the application of EOR techniques based on the specific characteristics of mature oil fields. In the final chapter, the conclusion and summary of the project will be provided, summarizing the key findings, implications, and contributions of the research. The conclusion will also outline potential areas for future research and development in the field of enhanced oil recovery for mature oil fields. Overall, this research project on "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to contribute valuable insights and recommendations to the petroleum industry, helping operators and decision-makers enhance the productivity and sustainability of mature oil fields through the application of advanced EOR technologies.
