Course Description

This program is aimed at people who are in critical well control positions during well intervention operations.  The course covers topics such as well control methods and influx characteristics. Shut-in procedure is also discussed.

This course is only a preparation for the IWCF certification. The fee does not include practical and written assessments. Certification application is to be done by the participants.
