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

Thesis Abstract

Abstract
This thesis investigates Enhanced Oil Recovery (EOR) techniques for mature oil fields through a comparative study to identify the most effective methods for maximizing oil extraction. The study focuses on understanding the challenges faced in mature oil fields, exploring various EOR techniques, and analyzing their applicability and effectiveness in different scenarios. The research methodology involves a comprehensive literature review, data collection from case studies, and analysis of field performance to draw comparisons between different EOR methods. The introduction provides an overview of the importance of EOR in enhancing oil production from mature fields and sets the context for the study. The background of the study delves into the characteristics of mature oil fields and the declining production rates associated with them. The problem statement highlights the need for improved recovery methods to optimize production from mature fields. The objectives of the study include evaluating existing EOR techniques, comparing their performance, and recommending the most suitable methods for mature oil fields. The literature review in Chapter Two presents a detailed analysis of ten key EOR techniques, including water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. Each method is examined in terms of its principles, applications, advantages, limitations, and success stories in the industry. The review provides a comprehensive understanding of the different EOR techniques and their potential for enhancing oil recovery in mature fields. Chapter Three outlines the research methodology employed in this study, including data collection methods, case study selection criteria, and analysis techniques. The methodology section details how the comparative study was conducted, the parameters considered, and the criteria for evaluating the performance of EOR techniques in mature oil fields. The chapter also discusses the limitations of the study and the steps taken to ensure the reliability and validity of the findings. Chapter Four presents a detailed discussion of the findings from the comparative study, highlighting the performance of various EOR techniques in mature oil fields. The chapter analyzes the effectiveness of each method based on factors such as oil recovery efficiency, cost-effectiveness, environmental impact, and operational challenges. The discussions provide insights into the strengths and weaknesses of different EOR techniques and their suitability for specific reservoir conditions. In Chapter Five, the conclusion summarizes the key findings of the study and offers recommendations for implementing EOR techniques in mature oil fields. The conclusion also discusses the implications of the study for the petroleum industry, potential areas for further research, and the significance of utilizing EOR methods to maximize oil recovery from mature fields. Overall, this thesis contributes to the existing knowledge on EOR techniques for mature oil fields by providing a comparative analysis of different methods and offering insights into their practical applications. The findings of this study can help oil companies and operators make informed decisions on selecting the most appropriate EOR techniques to optimize production and extend the economic life of mature oil fields.
