Optimization of Enhanced Oil Recovery Techniques in Offshore Reservoirs

Thesis Abstract

Abstract
The petroleum industry plays a crucial role in meeting the global energy demand, with offshore reservoirs being significant sources of oil production. Enhanced Oil Recovery (EOR) techniques have been developed to maximize oil extraction from these reservoirs. This thesis focuses on the optimization of EOR techniques in offshore reservoirs to improve production efficiency and recovery rates. The study aims to identify the most effective EOR methods and strategies for offshore operations, addressing challenges specific to offshore environments. The research begins with an introduction that provides background information on offshore oil production, highlighting the importance of EOR techniques in maximizing recovery rates. The problem statement emphasizes the need for optimized EOR strategies to address declining production rates in offshore reservoirs. The objectives of the study include evaluating existing EOR methods, identifying opportunities for optimization, and developing guidelines for implementing optimized EOR techniques in offshore operations. Limitations of the study are acknowledged, including constraints related to data availability, technology limitations, and offshore operational challenges. The scope of the study focuses on offshore reservoirs worldwide, considering various EOR techniques such as water flooding, gas injection, and chemical flooding. The significance of the study lies in its potential to enhance oil recovery rates, increase production efficiency, and contribute to sustainable energy production. The thesis structure comprises several chapters, including an introduction, literature review, research methodology, discussion of findings, and conclusion. The literature review covers ten key areas related to EOR techniques, offshore reservoir characteristics, and optimization strategies. The research methodology details the approach taken to evaluate and optimize EOR techniques in offshore reservoirs, including data collection, analysis, and simulation studies. The discussion of findings presents the results of the research, highlighting the most effective EOR methods and strategies for offshore reservoirs. Key findings include the impact of reservoir characteristics on EOR performance, the importance of well placement and design in offshore operations, and the role of advanced technologies in optimizing EOR processes. In conclusion, the study provides a comprehensive analysis of EOR optimization in offshore reservoirs, offering insights into best practices and recommendations for industry stakeholders. The thesis contributes to the advancement of EOR technologies in offshore oil production, supporting sustainable energy development and resource management. Further research is recommended to explore additional optimization opportunities and address evolving challenges in offshore oil recovery.
