Instructor: Dr. Tarek Ahmed

Designed for:

This course is designed for petroleum engineers and other technical professionals who are interested in understanding the properties and volumetric behavior of reservoir fluids under varying reservoir pressures and temperatures.

Course Overview:

The course is designed to provide engineers and other technical professionals with basic and advanced concepts in phase behavior and PVT analysis. The participant will be exposed to a comprehensive treatment of equations of state, applications, and proper tuning. Flow assurance and related topics will be covered in the course.

The participants will be given and have access to two software that will be used as an integral part of the course materials. Participants are encouraged to bring their computers for the classroom exercises.
