Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
The oil industry plays a pivotal role in the global economy, with the demand for energy continuing to rise. As conventional oil reserves deplete, the focus has shifted towards maximizing recovery from mature oil fields through Enhanced Oil Recovery (EOR) techniques. This thesis explores various EOR techniques and their application in mature oil fields to increase oil production and extend the economic life of reservoirs. Chapter One provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. The necessity for optimizing oil recovery from mature fields is emphasized, setting the stage for the subsequent chapters. Chapter Two presents a comprehensive literature review on EOR techniques, including thermal methods such as steam injection, chemical methods like polymer and surfactant flooding, and gas injection methods such as CO2 and nitrogen injection. The review highlights the principles, benefits, challenges, and case studies of each technique, offering valuable insights into their effectiveness in mature oil fields. Chapter Three details the research methodology, covering aspects such as data collection methods, experimental design, simulation techniques, reservoir characterization, fluid analysis, and economic evaluation models. The chapter outlines the systematic approach adopted to evaluate the performance of different EOR techniques in mature oil fields, ensuring the reliability and validity of the study. Chapter Four presents a detailed discussion of the findings obtained from the research, analyzing the effectiveness of various EOR techniques in enhancing oil recovery from mature fields. The chapter evaluates key performance indicators such as incremental oil production, sweep efficiency, recovery factor, and economic viability, providing a comparative analysis of different EOR methods. Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research results, and offering recommendations for future studies and practical applications in the oil industry. The conclusion highlights the significance of EOR techniques in maximizing oil recovery from mature fields and underscores the importance of continued research and innovation in this field. In conclusion, this thesis contributes to the existing body of knowledge on EOR techniques for mature oil fields, offering valuable insights for oil industry professionals, researchers, and policymakers. By exploring the potential of different EOR methods and their practical application in mature reservoirs, this research aims to support sustainable energy development and resource optimization in the oil sector.
