Objectives:
The course aims to equip participants with the knowledge to evaluate, design, and implement chemical EOR strategies—including polymer flooding, surfactant injection, and alkaline methods. Emphasis is placed on selecting appropriate chemicals, understanding reservoir conditions, and optimizing recovery performance.
Audience:
The course is designed for reservoir engineers, production engineers, EOR specialists, project managers, and technical professionals involved in field development planning, chemical injection programs, or optimization of mature fields.
Methodology:
Delivered through online live sessions, the course combines theoretical instruction with interactive discussions and field case studies. Concepts are reinforced via practical examples and simulation-based analysis to ensure applicability in real operational contexts.
Scope:
This course provides a comprehensive understanding of chemical enhanced oil recovery (EOR) methods, focusing on their theoretical background, chemical formulations, mechanisms, and field applications. It bridges the gap between laboratory research and real-world implementation, tailored to both sandstone and carbonate reservoirs.
