The IWCF Level 4 course is essential training for those working in wellsite supervisory roles and for office-based personnel that are primarily involved in the operational decision-making process and/or well design. The course aims to build on Level 3 course content (including barrier identification and shut-in based on given rig up) and focus on more complex aspects of well control and well kill methodology. 

Please visit the IWCF website for information about the program and the full course syllabus.


IWCF training levels 2 to 4 are designed to be sequential and first-time candidates are expected to complete Level 3 before progressing to Level 4. However, the training levels are also designed to be role-specific and dependent on the candidate’s work experience. For guidance and advice on which level of training you are eligible for, please get in touch.
