Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Study

Thesis Abstract

Abstract
This thesis presents a comprehensive study on Enhanced Oil Recovery (EOR) techniques tailored for mature oilfields. The oil and gas industry relies heavily on mature oilfields for sustaining production levels, making it crucial to explore innovative approaches to maximize oil recovery. The primary objective of this research is to conduct a comparative analysis of various EOR methods to identify the most effective strategies for enhancing oil recovery in mature oilfields. The introductory chapter sets the stage by providing an overview of the research background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter two delves into a detailed literature review encompassing ten critical areas related to EOR techniques, including water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies. Chapter three outlines the research methodology employed in this study, covering aspects such as research design, data collection methods, sampling techniques, data analysis procedures, and the selection criteria for case studies. The methodology aims to provide a robust framework for conducting a comparative analysis of EOR techniques in mature oilfields. In chapter four, the findings of the comparative study are discussed in detail, highlighting the key insights derived from the analysis of different EOR methods. This chapter presents a comprehensive evaluation of the performance, cost-effectiveness, and environmental impact of various EOR techniques, providing valuable insights for decision-makers in the oil and gas industry. Finally, chapter five presents the conclusion and summary of the thesis, encapsulating the key findings, implications, and recommendations derived from the study. The research findings emphasize the importance of adopting tailored EOR strategies for mature oilfields to optimize oil recovery, extend field life, and maximize economic returns. Overall, this thesis contributes to the existing body of knowledge in the field of petroleum engineering by offering a comparative analysis of EOR techniques for mature oilfields. The insights derived from this study can inform industry practitioners, policymakers, and researchers on the most effective strategies for enhancing oil recovery in mature oilfields, thereby contributing to sustainable energy production and resource management in the oil and gas sector.
