Description
The IWCF DWC level 2 course provides a basic understanding of the fundamental principles involved in maintaining well control.
The course is delivered through interactive lecturing supported by videos, animations, group discussions and exercises.
Candidates can select either the surface BOP or the Combined surface and subsea BOP program.

Audience
Level 2 training is recommended as a basic level well control training module.
Attendees should be any members of the well-site operations teams engaged in office-based oversight and 24/7 well monitoring centers, and those who work in on-site roles which could directly contribute to the creation, detection, or control of a well influx or lack of well integrity.
