Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
The depletion of conventional oil reserves has led to a growing interest in maximizing oil recovery from mature oil fields through enhanced oil recovery (EOR) techniques. This thesis explores various EOR techniques that can be applied to mature oil fields to increase oil production and extend the economic life of these assets. The study begins with an overview of the current state of mature oil fields and the challenges they face in terms of declining production rates and increasing operating costs. The research methodology involves a comprehensive literature review to identify and analyze the most suitable EOR techniques for mature oil fields. Chapter Two provides an in-depth literature review of ten key EOR techniques commonly used in the petroleum industry. This review covers the principles, advantages, and limitations of techniques such as water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. The analysis aims to evaluate the effectiveness of each technique in enhancing oil recovery from mature oil fields based on case studies and research findings. Chapter Three outlines the research methodology employed in this study, including the selection criteria for EOR techniques, data collection methods, and the criteria for evaluating the feasibility and applicability of each technique to mature oil fields. The methodology also includes a detailed description of the simulation models used to assess the performance of selected EOR techniques and predict their impact on oil recovery rates. Chapter Four presents a detailed discussion of the findings obtained from the literature review and simulation studies. The chapter highlights the key factors influencing the selection and implementation of EOR techniques in mature oil fields, such as reservoir characteristics, fluid properties, economic considerations, and environmental impact. The discussion also addresses the challenges and limitations associated with implementing EOR techniques in real-world oil field operations. Chapter Five offers a comprehensive conclusion and summary of the thesis, summarizing the key findings, implications, and recommendations for future research and practical applications. The study underscores the importance of adopting tailored EOR strategies for mature oil fields to optimize oil recovery, increase production efficiency, and maximize economic returns. The research contributes to the body of knowledge on EOR techniques for mature oil fields and provides valuable insights for industry stakeholders and decision-makers seeking to enhance oil recovery from aging oil assets.
