Enhanced Oil Recovery Techniques for Mature Oilfields: A Case Study Analysis

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon extraction from mature oilfields. This thesis presents a comprehensive case study analysis focusing on various EOR methods applied to mature oilfields to improve recovery rates and extend the economic lifespan of the reservoirs. The research investigates the effectiveness of different EOR techniques, such as thermal, chemical, and gas injection methods, in enhancing oil recovery from mature oilfields through a detailed examination of real-world case studies. Chapter One provides an introduction to the research topic, outlining the background of the study, defining the problem statement, objectives, limitations, scope, significance of the study, structure of the thesis, and key definitions of terms related to EOR techniques in mature oilfields. Chapter Two consists of a thorough literature review that examines existing studies, theories, and practices related to EOR techniques, providing a comprehensive overview of the current state of knowledge in the field. Chapter Three details the research methodology employed in this study, including data collection methods, research design, sampling techniques, data analysis procedures, and the tools used to evaluate the effectiveness of EOR techniques in mature oilfields. This chapter also discusses the limitations and potential biases that may affect the research findings. In Chapter Four, the research findings are presented and analyzed in detail, focusing on the application of different EOR techniques in specific mature oilfield cases. The discussion delves into the challenges, successes, and lessons learned from the implementation of EOR methods, highlighting the factors that influence their effectiveness in enhancing oil recovery rates. Finally, Chapter Five provides a conclusion and summary of the thesis, summarizing the key findings, discussing the implications of the research results, and offering recommendations for future studies and practical applications in the field of EOR for mature oilfields. The thesis concludes with a reflection on the significance of the research outcomes and their contribution to the advancement of EOR technologies in the oil and gas industry. Overall, this thesis aims to provide valuable insights into the application of EOR techniques in mature oilfields, offering a comprehensive analysis of their impact on oil recovery rates and reservoir performance. By examining real-world case studies, this research contributes to the body of knowledge on EOR methods and their potential to optimize hydrocarbon extraction from mature oilfields, ultimately supporting sustainable energy production and resource management in the oil and gas sector.
