Instructor: Dr. Tarek Ahmed
Objective:
A 5-Day course that is designed to provide engineering with basic and advanced
concepts in phase behavior, understanding PVT laboratory analysis, and
performing QC/quality assurance tests on laboratory data. 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.
Requirements:
- Participants are encouraged to bring their own laboratory data to discuss with the instructor
- Participants are required to bring their own laptop computers
- Participants will receive a PVT software
- Participants are encouraged to bring field data to perform field optimization and developments
