Thesis Abstract

Abstract
The oil and gas industry plays a crucial role in the global energy sector, with conventional reservoirs being the primary source of hydrocarbon production for decades. However, as conventional reservoirs mature and production declines, attention has shifted towards unconventional reservoirs. Enhanced Oil Recovery (EOR) techniques have become essential in maximizing hydrocarbon recovery from these unconventional reservoirs. This thesis explores various EOR techniques specifically tailored for unconventional reservoirs, aiming to improve recovery efficiency and increase overall production. Chapter One provides an introduction to the study, outlining the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. The increasing importance of EOR in unconventional reservoirs is highlighted, setting the stage for a comprehensive examination of innovative recovery techniques. Chapter Two presents a thorough literature review on EOR techniques for unconventional reservoirs. The chapter covers ten key areas, including the characteristics of unconventional reservoirs, existing EOR methods, challenges faced in unconventional EOR, and recent advancements in the field. By synthesizing existing knowledge, this chapter provides a solid foundation for the subsequent research methodology. Chapter Three delves into the research methodology employed in this study. The chapter outlines the research design, data collection methods, analysis techniques, and the selection criteria for case studies. Eight components are detailed, including the experimental approach, simulation models, and field trial methodologies. The methodology aims to investigate the feasibility and effectiveness of various EOR techniques in unconventional reservoirs. Chapter Four presents an in-depth discussion of the findings derived from the research methodology. The chapter analyzes the results of the case studies, simulation models, and field trials to evaluate the performance of different EOR methods in unconventional reservoirs. Factors such as reservoir heterogeneity, fluid properties, and operational considerations are considered in assessing the success and challenges of implementing EOR techniques. Finally, Chapter Five offers a conclusion and summary of the thesis. The chapter synthesizes the key findings, discusses the implications of the research, and offers recommendations for future studies and industry applications. The thesis concludes by emphasizing the importance of continued research and innovation in EOR techniques for unconventional reservoirs to meet the growing energy demands sustainably. In conclusion, this thesis contributes to the evolving field of EOR by focusing on the specific challenges and opportunities present in unconventional reservoirs. By exploring innovative techniques and methodologies, this study aims to enhance recovery efficiency and pave the way for sustainable hydrocarbon production in unconventional reservoirs.

Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Unconventional Reservoirs" aims to explore and analyze advanced methods of recovering oil from unconventional reservoirs, which play a crucial role in the global energy industry. Unconventional reservoirs, such as shale formations, tight sandstones, and heavy oil deposits, pose unique challenges due to their complex geology and low permeability. Traditional oil recovery methods are often insufficient in extracting the maximum amount of oil from these reservoirs, making enhanced oil recovery (EOR) techniques essential for maximizing production efficiency. The research will begin with a comprehensive introduction outlining the background of the study, the problem statement, research objectives, limitations, scope, significance, and the overall structure of the thesis. This will set the foundation for understanding the importance of exploring EOR techniques specifically tailored for unconventional reservoirs. The literature review in Chapter Two will delve into existing research and technologies related to EOR in unconventional reservoirs. It will explore various EOR methods, such as thermal, chemical, and gas injection techniques, highlighting their advantages and limitations in different types of unconventional reservoirs. The review will also analyze case studies and best practices in the industry to provide a thorough understanding of the current state-of-the-art in EOR for unconventional reservoirs. Chapter Three will focus on the research methodology, detailing the approach, data collection methods, experimental procedures (if applicable), and analytical techniques used to investigate and evaluate the effectiveness of different EOR techniques in unconventional reservoirs. The chapter will also discuss the criteria for selecting the most suitable EOR method based on reservoir characteristics, economic feasibility, and environmental impact. Chapter Four will present a detailed discussion of the research findings, including the performance evaluation of various EOR techniques in unconventional reservoirs. The analysis will highlight the key factors influencing the success of EOR projects, such as reservoir heterogeneity, fluid properties, wellbore integrity, and operational challenges. The chapter will also address the implementation strategies and potential solutions to overcome barriers to effective EOR in unconventional reservoirs. Finally, Chapter Five will provide a conclusive summary of the research outcomes, emphasizing the significance of the findings and their implications for the oil and gas industry. The chapter will also offer recommendations for future research directions and practical applications of EOR techniques to enhance oil recovery from unconventional reservoirs. Overall, this research project on "Enhanced Oil Recovery Techniques for Unconventional Reservoirs" aims to contribute valuable insights to the field of petroleum engineering by advancing our understanding of innovative EOR methods tailored for challenging reservoir conditions. The findings and recommendations from this study have the potential to optimize oil production, increase energy security, and promote sustainable development in the global oil and gas sector."
