Optimization of Enhanced Oil Recovery Techniques in Mature Oil Fields

Thesis Abstract

Abstract
The optimization of enhanced oil recovery (EOR) techniques in mature oil fields is a critical aspect of petroleum engineering that aims to maximize oil production from reservoirs that have already undergone primary and secondary recovery methods. This thesis investigates various EOR techniques and their application in mature oil fields to enhance oil recovery efficiency and ultimately increase oil production. The study focuses on the challenges faced in mature fields, such as declining production rates and increasing operating costs, and explores how the implementation of optimized EOR methods can address these challenges. The research begins with an introduction that outlines the background of the study, the problem statement, objectives, limitations, scope, significance, and the structure of the thesis. A comprehensive literature review in Chapter Two examines ten key studies related to EOR techniques in mature oil fields, providing insights into the current state of research and highlighting gaps in knowledge that this study seeks to address. Chapter Three details the research methodology employed in this study, including data collection methods, analysis techniques, and experimental procedures. The chapter covers eight key contents, such as the selection criteria for mature oil fields, data collection processes, simulation modeling, and economic evaluation methods. In Chapter Four, the findings of the study are discussed in detail, presenting the results of the application of optimized EOR techniques in mature oil fields. The chapter explores the impact of these techniques on oil recovery efficiency, production rates, and overall field performance. Additionally, the challenges encountered during the implementation of EOR methods are analyzed, and recommendations for overcoming these challenges are provided. Finally, Chapter Five presents the conclusion and summary of the thesis, highlighting the key findings, implications for the petroleum industry, and recommendations for future research. The study concludes that the optimization of EOR techniques in mature oil fields has the potential to significantly increase oil recovery rates and extend the productive life of reservoirs, making it a crucial strategy for sustainable oil production. In summary, this thesis contributes to the existing body of knowledge on EOR techniques in mature oil fields and provides valuable insights for petroleum engineers, researchers, and industry professionals seeking to enhance oil recovery efficiency and maximize production from mature reservoirs. The findings of this study have important implications for the sustainable development of oil fields and can guide future research and practical applications in the field of petroleum engineering.
