Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing oil production from mature oil fields. This thesis focuses on investigating and analyzing various EOR techniques to enhance oil recovery in mature oil fields. The study begins with a comprehensive review of the background and problem statement, highlighting the challenges faced in mature oil fields and the importance of implementing effective EOR techniques. The objectives of the study are to evaluate different EOR methods, assess their applicability in mature oil fields, and provide recommendations for optimizing oil recovery. The literature review in Chapter Two explores ten key studies on EOR techniques, including water flooding, chemical flooding, gas injection, thermal methods, and microbial EOR. Each method is analyzed in terms of its effectiveness, limitations, and field applications. Chapter Three details the research methodology, covering aspects such as data collection, analysis techniques, simulation models, and experimental design. The chapter also outlines the selection criteria for case studies and the approach to evaluating the performance of EOR techniques in mature oil fields. Chapter Four presents a detailed discussion of the findings from the case studies and analysis of different EOR techniques. The chapter evaluates the success of each method in improving oil recovery, considering factors such as reservoir characteristics, fluid properties, and operational challenges. The results provide valuable insights into the practical implementation and optimization of EOR techniques in mature oil fields. Finally, Chapter Five summarizes the key findings of the study and presents conclusions based on the analysis of EOR techniques for mature oil fields. The study emphasizes the significance of adopting integrated and tailored EOR strategies to maximize oil recovery and extend the economic life of mature oil fields. Recommendations for future research and practical implications for the oil industry are also discussed. In conclusion, this thesis contributes to the knowledge base of EOR techniques for mature oil fields by providing a comprehensive analysis of various methods, their performance, and the factors influencing their success. The findings offer valuable insights for oil field operators, reservoir engineers, and researchers seeking to optimize oil recovery in mature fields through the application of advanced EOR techniques.
