Development and Optimization of Enhanced Oil Recovery Techniques for Unconventional Reservoirs

Thesis Abstract

Abstract
The exploration and production of oil from unconventional reservoirs play a crucial role in meeting the global energy demand. However, the recovery of oil from such reservoirs is often challenging due to the complex nature of the rock formations. This thesis focuses on the development and optimization of enhanced oil recovery (EOR) techniques specifically tailored for unconventional reservoirs. The objective is to improve the efficiency and effectiveness of oil recovery processes in these challenging environments. The study begins with an in-depth examination of the background of unconventional reservoirs, highlighting the unique characteristics that differentiate them from conventional reservoirs. The problem statement underscores the existing limitations and challenges faced in recovering oil from unconventional reservoirs, setting the stage for the research objectives. The primary objective of this study is to develop and optimize EOR techniques that are suitable for enhancing oil recovery from unconventional reservoirs. The limitations and scope of the study are clearly defined to provide a comprehensive understanding of the research boundaries. The significance of the study is emphasized, highlighting the potential impact of the developed EOR techniques on the oil and gas industry. The structure of the thesis is outlined to guide the reader through the various chapters and sections of the research document. Finally, key terms and definitions are provided to ensure clarity and understanding of the technical terminology used throughout the thesis. In the literature review chapter, a comprehensive analysis of existing research and studies related to EOR techniques for unconventional reservoirs is presented. Ten key areas of literature are explored, covering topics such as reservoir characterization, fluid dynamics, rock mechanics, and EOR methods. The review of literature provides a solid foundation for the subsequent research methodology chapter. The research methodology chapter details the approach taken to develop and optimize EOR techniques for unconventional reservoirs. Eight key components of the methodology are discussed, including reservoir simulation, laboratory experiments, data analysis, and optimization techniques. The methodology is designed to be rigorous and systematic, ensuring the reliability and validity of the research findings. Chapter four presents a detailed discussion of the research findings, including the performance evaluation of the developed EOR techniques in unconventional reservoirs. The findings are analyzed and interpreted to assess the effectiveness of the optimized EOR methods in enhancing oil recovery rates. The discussion also addresses any challenges encountered during the research process and provides recommendations for future studies in this field. In the final chapter, the conclusions drawn from the research findings are summarized, highlighting the key insights and contributions of the study. The significance of the developed EOR techniques for the oil and gas industry is reiterated, emphasizing their potential to improve oil recovery efficiency and maximize production from unconventional reservoirs. The thesis concludes with recommendations for further research and practical applications of the optimized EOR techniques in real-world reservoirs. In conclusion, this thesis provides a comprehensive analysis of the development and optimization of enhanced oil recovery techniques for unconventional reservoirs. The research findings contribute to the advancement of EOR technologies and offer valuable insights for improving oil recovery processes in challenging reservoir environments.
