Objective:

This is an in-depth 5-day course that is designed to provide the participants with a solid and in depth understanding of reservoir engineering and associated modern theories in order to manage and maximize hydrocarbon recovery. Hands-on examples and exercises are used throughout the course to help participants with understanding key concepts. Participants are encouraged to bring reservoir data to discuss in class.
