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.

Thesis Overview

The research project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to investigate and analyze various advanced techniques that can be employed to enhance oil recovery in mature oil fields. Mature oil fields are those that have been in production for an extended period and have experienced a decline in production rates. As traditional extraction methods become less effective in these fields, there is a need to explore innovative approaches to maximize oil recovery and extend the economic life of these reservoirs. The project will begin with a comprehensive literature review that examines existing enhanced oil recovery (EOR) techniques such as water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. By reviewing the current state-of-the-art technologies and analyzing successful case studies, the study aims to identify the most promising approaches for enhancing oil recovery in mature fields. Following the literature review, the research methodology will be developed to investigate the feasibility and effectiveness of implementing selected EOR techniques in a specific mature oil field. This will involve conducting simulations and modeling studies to assess the potential impact of different EOR methods on oil recovery rates, production costs, and environmental considerations. Field tests and pilot projects may also be conducted to validate the findings of the simulation studies. The project will then move on to a detailed discussion of the findings, where the results of the simulations and field tests will be analyzed and interpreted. The effectiveness of each EOR technique will be evaluated based on factors such as incremental oil recovery, production efficiency, cost-effectiveness, and environmental impact. The discussion will also address any challenges and limitations encountered during the implementation of the EOR techniques in the mature oil field. In the conclusion and summary chapter, the key findings of the study will be summarized, and recommendations for future research and practical applications will be provided. The project aims to contribute to the body of knowledge in the field of petroleum engineering by identifying innovative EOR techniques that can be effectively applied to enhance oil recovery in mature oil fields. The ultimate goal is to provide valuable insights and solutions to the industry to optimize oil production and maximize the economic potential of mature reservoirs.
