Well Test Analysis Course

X:XX Hours
The objective of the Well Test Analysis course is to provide a comprehensive theoretical and practical knowledge of well test analysis techniques. Emphasis will be placed on the practical aspects of well testing and numerous class examples and case studies are offered.

Further, the use of the test analysis results as a reservoir management tool to make decisions related to reservoir development and well completion will be illustrated through actual case studies throughout the class. Recent developments in testing of Multi-stage Frac of Horizontal Wells (MFHW’s) and Mini frac (DFIT), Rate Transient Analysis (RTA), multi-phase analysis, and the analysis of Inflow Control Devices (ICD) are now included.. A detailed course hand-out, which is an excellent reference, will be provided.

Who Should Attend?
This course is aimed at reservoir, petroleum, and exploitation engineers/technologists. Other discipline staff such as geophysicists and geologists who are involved in the field development and exploitation will also benefit from this course.
