After completing this course, participants will have the knowledge required to pass the IWCF Certification test. The IWCF Certification in Norway is a government imposed certificate for leading well service personnel and must be renewed every two years.

Course Content

- Self-study before the course starts

- Teaching and assignments

- Practical exercises on simulator

- The course ends with IWCF certification test

- Main reasons for well bore kick

- Interpretation of welll bore signals indicating a kick

- Shut-in procedures

- Well control calculations

- Circulations methods

- Simulator exercises

This introductory course provides the drilling personnel with basic understanding of well control. Progressing junior staff get a solid background and knowledge of why well control is essential, how well control is maintained, what the indicators are that well control might be lost, and how to regain the control once it has been lost.

Understand the negative consequences associated with loss of well control
Understand the need for detection
Recognize the warning signs of abnormal pressure
Know the actions that should be taken when kick indicators are present
Be familiar with the functions of the bop equipment
Be able to select well control method to regain control
Be able to fill in a IWCF surface and/or subsea kill sheet
Be able to calculate kill mud weight, initial circulation pressure and final circulation pressure
Correctly obtain shut in pressures in the well
Understand the barrier concept
Know the impact pumping cement could have on well control
Obtain sufficient knowledge to pass a written IWCF test with minimum 70% score

The most common well problems
Upon completion of this course, participants should be able to give an account of the construction process of a production well, and the equipment that is used for completion. In addition to this, they should be able to describe the most common problems that affect wells, as well as giving an account of how these can be solved.
