Enhanced Oil Recovery Techniques: A Comparative Study of Chemical Flooding and Steam Injection

Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the application of enhanced oil recovery (EOR) techniques, specifically focusing on chemical flooding and steam injection methods. The study aims to compare and analyze the effectiveness of these two EOR methods in increasing oil production from mature reservoirs. The research is motivated by the growing importance of maximizing oil recovery rates and optimizing production processes in the petroleum industry. The introduction provides background information on the challenges faced by the oil and gas industry, particularly in the context of declining production rates in mature reservoirs. The problem statement highlights the need for innovative EOR techniques to enhance oil recovery and extend the economic viability of existing oil fields. The objectives of the study include evaluating the performance of chemical flooding and steam injection methods, identifying key factors influencing their efficiency, and providing recommendations for optimal EOR strategies. The literature review section examines existing research on EOR techniques, with a particular focus on chemical flooding and steam injection. Ten key areas are explored, including the mechanisms of oil displacement, reservoir characterization, operational considerations, economic aspects, and environmental impacts. This review serves as a foundation for understanding the current state of knowledge and identifying gaps that warrant further investigation. The research methodology section outlines the approach taken to conduct the comparative study of chemical flooding and steam injection. Eight key components are discussed, covering aspects such as data collection, experimental design, simulation modeling, performance evaluation criteria, and uncertainty analysis. The methodology aims to provide a rigorous and systematic framework for evaluating the effectiveness of the two EOR methods and drawing meaningful conclusions from the results. The discussion of findings chapter presents a detailed analysis of the research outcomes, comparing the performance of chemical flooding and steam injection in terms of oil recovery efficiency, production rates, cost-effectiveness, and environmental considerations. The findings shed light on the advantages and limitations of each EOR method and offer insights into factors influencing their success in different reservoir conditions. Finally, the conclusion and summary chapter provide a comprehensive overview of the study outcomes, highlighting key findings, implications for the petroleum industry, and recommendations for future research. The thesis contributes to the existing body of knowledge on EOR techniques and offers valuable insights for oil and gas companies seeking to optimize their production processes and maximize oil recovery from mature reservoirs.
