Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study

Thesis Abstract

Abstract
This thesis investigates Enhanced Oil Recovery (EOR) techniques for mature oil fields through a comparative study to enhance the recovery efficiency and sustainability of oil extraction. The study focuses on evaluating different EOR methods to determine their effectiveness and feasibility in mature oil fields. The research aims to address the challenges faced in mature oil fields, including declining production rates and diminishing reserves, by exploring innovative EOR strategies. The introductory chapter provides an overview of the background of the study, highlighting the importance of EOR in maximizing oil recovery from mature fields. The problem statement identifies the key issues faced in mature oil fields, emphasizing the need for advanced recovery techniques. The objectives of the study are outlined to guide the research process towards achieving specific goals and outcomes. A comprehensive literature review in Chapter Two examines existing studies and research findings on various EOR methods, including chemical, thermal, and gas injection techniques. The review synthesizes the advantages and limitations of each method, providing a basis for comparison in the subsequent analysis. Chapter Three presents the research methodology employed in this study, detailing the approach, data collection methods, and analysis techniques used to evaluate the effectiveness of different EOR techniques. The chapter also discusses the selection criteria for case studies and field trials conducted to assess the application of EOR methods in mature oil fields. The findings and results of the comparative study are discussed in Chapter Four, highlighting the performance and efficiency of different EOR techniques in enhancing oil recovery rates. The analysis includes a detailed examination of field trial data and case studies to demonstrate the practical application and outcomes of the selected EOR methods. The concluding chapter, Chapter Five, summarizes the key findings of the study and discusses their implications for the oil industry. The thesis concludes with recommendations for the adoption of specific EOR techniques based on their effectiveness and feasibility in mature oil fields. The research contributes to the advancement of EOR practices, offering insights into sustainable strategies for maximizing oil recovery and prolonging the productive life of mature oil fields. In conclusion, this comparative study provides valuable insights into the selection and implementation of EOR techniques for mature oil fields, offering practical solutions to overcome production challenges and optimize oil extraction processes. The research outcomes contribute to the development of sustainable practices in the oil and gas industry, with implications for enhancing energy security and resource utilization in the global context.
