Optimization of Enhanced Oil Recovery Techniques in Offshore Reservoirs

Thesis Abstract

Abstract
The optimization of enhanced oil recovery (EOR) techniques in offshore reservoirs is a critical component of petroleum engineering research, as it plays a significant role in maximizing oil production and extending the economic life of oil fields. This thesis focuses on investigating and optimizing various EOR techniques specifically tailored for offshore reservoirs, where the unique challenges and constraints of offshore operations necessitate innovative solutions for improving oil recovery efficiency. The study begins with a comprehensive introduction to the background of EOR techniques and the specific challenges associated with offshore reservoirs. The problem statement highlights the need for improved EOR strategies to address declining production rates in offshore fields. The objectives of the study are outlined to guide the research towards developing practical and effective EOR solutions for offshore applications. In conducting this research, various EOR methods such as chemical flooding, gas injection, and thermal methods are reviewed and analyzed to identify their applicability and effectiveness in offshore reservoirs. The literature review chapter presents a detailed analysis of existing studies, technologies, and best practices in EOR, providing a solid foundation for the subsequent research methodology chapter. The research methodology chapter outlines the approach taken to optimize EOR techniques in offshore reservoirs, including data collection, simulation modeling, laboratory experiments, and field trials. The methodology is designed to validate the effectiveness of selected EOR methods and optimize their implementation in offshore environments. The chapter also discusses the selection criteria for EOR techniques, simulation parameters, experimental setups, and data analysis methods. The findings chapter presents the results of the research, including the performance evaluation of different EOR methods in offshore reservoirs, comparative analysis of key parameters, and optimization strategies for maximizing oil recovery efficiency. The discussion of findings chapter provides a detailed analysis of the results, highlighting the strengths and limitations of each EOR technique and proposing recommendations for further optimization and field implementation. In conclusion, the thesis summarizes the key findings, implications, and contributions to the field of petroleum engineering. The study demonstrates the significance of optimizing EOR techniques in offshore reservoirs to enhance oil recovery rates, reduce production costs, and mitigate environmental impacts. The research outcomes provide valuable insights and practical recommendations for oil and gas operators, researchers, and policymakers seeking to improve the sustainability and profitability of offshore oil fields. Overall, this thesis contributes to advancing the knowledge and understanding of EOR optimization in offshore reservoirs, offering innovative solutions and best practices for maximizing oil production and extending the economic viability of offshore oil and gas assets.
