Course curriculum

Course Description:

This course is designed for oilfield professionals who need to conduct oilfield demulsifier bottle tests using a pre-designed procedure. Field emulsion evaluation using centrifugation method to break total water down to water at various phases in oilfield emulsions is explained in detail. Key bottle test equipment you would need are listed. The demulsifier bottle test procedure is discussed.

 

Designing a bottle test procedure and best practices of bottle tests are discussed in the Level 2 course.
