Objective:

This is an in-depth 5-day course that is designed to provide the participants with a solid and in depth understanding of waterflood calculations and waterflood surveillance in addition to the associated modern theories in order to manage and maximize hydrocarbon recovery. The course will also provide with in-depth illustration on applying waterflood Modern Decline Curve Analysis Methods. Hands-on examples and exercises are used throughout the course to help participants with understanding key concepts. It should be pointed out that participants are encouraged to bring reservoir data to discuss in class.
