Optimization of Enhanced Oil Recovery Techniques in Offshore Petroleum Reservoirs

Thesis Abstract

Abstract
The optimization of enhanced oil recovery (EOR) techniques in offshore petroleum reservoirs is a critical aspect of the petroleum engineering field, aimed at maximizing oil production and extending the life of existing reservoirs. This thesis explores various EOR methods and their application in offshore settings to enhance oil recovery efficiency. The study begins with an introduction to the importance of EOR in the petroleum industry and the specific challenges faced in offshore reservoirs. The background of the study provides a comprehensive overview of existing literature on EOR techniques and their effectiveness in offshore environments. The problem statement highlights the need for improved EOR strategies to overcome the limitations of traditional recovery methods in offshore petroleum reservoirs. The objectives of the study focus on evaluating the performance of different EOR techniques, identifying key factors influencing their efficiency, and developing a framework for optimizing EOR processes in offshore settings. The limitations of the study are discussed to provide a clear understanding of the scope and constraints of the research. The scope of the study encompasses a detailed analysis of ten selected EOR methods commonly used in offshore reservoirs, including water flooding, gas injection, chemical flooding, and thermal methods. The significance of the study lies in its potential to enhance oil recovery rates, reduce environmental impact, and increase the economic viability of offshore oil production. The structure of the thesis outlines the organization of the research work, including the chapters and sub-chapters that will be covered in the study. In the literature review chapter, ten key EOR techniques are critically analyzed based on their principles, applications, advantages, and limitations in offshore petroleum reservoirs. The research methodology chapter describes the approach taken to evaluate and compare the performance of these EOR methods, including data collection, analysis techniques, and simulation studies. Various factors such as reservoir characteristics, fluid properties, and operational considerations are considered in the research methodology to assess the effectiveness of each EOR technique. The discussion of findings chapter presents a detailed analysis of the performance of different EOR methods in offshore reservoirs, highlighting their strengths and weaknesses under varying conditions. The results of the study provide valuable insights into the optimal EOR strategies for maximizing oil recovery in offshore environments. The conclusion and summary chapter consolidate the key findings of the research, discuss their implications for the petroleum industry, and suggest recommendations for future studies in this field. Overall, this thesis contributes to the advancement of EOR techniques in offshore petroleum reservoirs by providing a comprehensive analysis of key methods, identifying opportunities for optimization, and offering insights into improving oil recovery efficiency in challenging offshore environments. The findings of this study have practical implications for oil companies, researchers, and policymakers seeking to enhance oil production sustainability and profitability in offshore fields.
