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

Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the application of enhanced oil recovery (EOR) techniques in mature oil fields, focusing on the comparative analysis of various methods to improve oil production efficiency and reservoir recovery. The study aims to address the challenges faced in mature oil fields, where conventional recovery methods have proven insufficient, and the need for more advanced techniques is evident. By comparing and evaluating different EOR methods, this research seeks to provide valuable insights into the most effective strategies for maximizing oil production in mature oil fields. The introductory chapter provides a detailed background of the study, highlighting the significance of EOR techniques in enhancing oil recovery from mature reservoirs. The problem statement identifies the limitations of conventional recovery methods and underscores the importance of exploring alternative approaches to optimize oil production. The objectives of the study are outlined to guide the research process, while the scope and limitations of the study delineate the boundaries within which the investigation will be conducted. Chapter Two presents a comprehensive literature review that examines existing research on EOR techniques, including water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies. The review synthesizes key findings and identifies gaps in the current knowledge, laying the foundation for the comparative analysis of EOR methods in mature oil fields. Chapter Three details the research methodology employed in this study, including data collection methods, experimental design, and analytical techniques. The chapter outlines the steps taken to compare and evaluate different EOR techniques, providing a transparent and systematic approach to the research process. Chapter Four presents the findings of the comparative analysis, showcasing the effectiveness of various EOR methods in improving oil recovery from mature oil fields. The discussion delves into the advantages and limitations of each technique, offering insights into their applicability and potential for enhancing reservoir performance. In the concluding chapter, Chapter Five, the key findings of the study are summarized, and the implications for the oil and gas industry are discussed. The thesis concludes with recommendations for future research and practical applications of EOR techniques in mature oil fields. Overall, this thesis contributes to the body of knowledge on EOR strategies for mature oil fields, providing valuable insights for oil and gas professionals, researchers, and policymakers seeking to optimize oil recovery and extend the productive life of mature reservoirs.
