Enhanced Oil Recovery Techniques for Sustainable Production in Mature Oil Fields

Thesis Abstract

Abstract
The oil and gas industry continues to face challenges in sustaining production levels in mature oil fields. Enhanced oil recovery (EOR) techniques have emerged as a promising solution to maximize hydrocarbon extraction efficiency and prolong the economic lifespan of these fields. This thesis explores various EOR techniques and their applications in mature oil fields to achieve sustainable production levels. The study focuses on understanding the background of EOR, identifying the problems faced in mature oil fields, setting clear objectives, acknowledging limitations, defining the scope, and highlighting the significance of the study. Chapter One provides the foundation for the research, starting with an introduction to the importance of EOR in mature oil fields. The background of the study delves into the evolution of EOR techniques and their relevance in the current oil and gas landscape. The problem statement highlights the challenges faced in mature oil fields and the need for innovative solutions. Objectives are set to investigate different EOR methods, evaluate their effectiveness, and propose strategies for sustainable production. Limitations and scope of the study are outlined to provide a clear focus, while the significance of the research emphasizes the potential impact on the industry. The chapter concludes with the structure of the thesis and a comprehensive definition of key terms. Chapter Two presents a detailed literature review covering ten key aspects related to EOR techniques in mature oil fields. This section explores the history of EOR, different methods such as chemical, thermal, and miscible flooding, reservoir characterization, economic considerations, environmental impacts, case studies, challenges, and future trends. By synthesizing existing knowledge, this chapter provides a solid theoretical framework for understanding the complexities of EOR implementation. Chapter Three outlines the research methodology, including the research design, data collection methods, sampling techniques, data analysis procedures, and ethical considerations. The chapter also discusses the selection criteria for case studies and simulation models used to evaluate EOR performance in mature oil fields. The methodology is designed to ensure rigor and reliability in the research process. Chapter Four presents a comprehensive discussion of the findings obtained from the research. This section analyzes the effectiveness of various EOR techniques in enhancing oil recovery rates and sustaining production levels in mature fields. Case studies and simulation results are critically evaluated to identify best practices and potential areas for improvement. The chapter also discusses the economic viability and environmental implications of implementing EOR technologies. Chapter Five concludes the thesis by summarizing the key findings, discussing their implications for the industry, and offering recommendations for future research and practical applications. The study underscores the importance of adopting sustainable EOR techniques to address the challenges faced in mature oil fields and ensure long-term viability in oil production. By integrating theoretical insights with practical considerations, this research contributes to the advancement of EOR practices and supports the goal of achieving sustainable production in mature oil fields.
