Optimization of Enhanced Oil Recovery Techniques in Unconventional Reservoirs

Thesis Abstract

Abstract
The optimization of enhanced oil recovery (EOR) techniques in unconventional reservoirs has become a critical area of research in the petroleum engineering field. Unconventional reservoirs, such as tight oil and gas formations, shale formations, and coalbed methane reservoirs, present unique challenges due to their complex geological characteristics and low primary recovery rates. This thesis aims to investigate and propose innovative strategies to enhance oil recovery from unconventional reservoirs through optimization techniques. Chapter One provides an introduction to the research topic, background information on EOR techniques, a detailed problem statement, research objectives, limitations, scope, significance of the study, structure of the thesis, and definitions of key terms related to the research. Chapter Two presents a comprehensive literature review on EOR techniques in unconventional reservoirs. The chapter discusses ten key concepts, including the types of unconventional reservoirs, existing EOR methods, challenges in implementing EOR in unconventional reservoirs, and recent advancements in the field. Chapter Three outlines the research methodology employed in this study. It includes detailed descriptions of the research design, data collection methods, data analysis techniques, simulation models used, laboratory experiments conducted, field trials, and any other methodologies utilized to achieve the research objectives. Chapter Four presents a thorough discussion of the findings obtained from the research. This chapter delves into the optimization strategies proposed, the results of numerical simulations and experiments, comparisons between different EOR techniques, economic evaluations, environmental impact assessments, and the practical implications of the findings. Chapter Five serves as the conclusion and summary of the thesis. It provides a recap of the research objectives, a summary of the key findings, implications for the petroleum industry, recommendations for future research, and conclusions drawn from the study. The chapter also reflects on the significance of the research in advancing the field of enhanced oil recovery in unconventional reservoirs. In conclusion, this thesis contributes to the knowledge base of petroleum engineering by offering innovative solutions for optimizing enhanced oil recovery techniques in unconventional reservoirs. The research findings and recommendations have the potential to enhance oil production rates, improve reservoir performance, and increase the economic viability of extracting hydrocarbons from challenging unconventional reservoirs.
