Instructor: Dr. Tarek Ahmed

Designed for:

A 5-day course that is designed for the G&G staff as well as a refresher course for petroleum engineers. The course presents fundamental aspects of reservoir engineering to the G&G staff to understand the type of issues that the reservoir engineer faces and the tools he uses to conduct viable reservoir engineering study. The participants will be exposed to basic reservoir simulation through Hands-on simulation studies.
