Overview
Gives junior drilling staff the common formulas and calculations used in the oilfield, and introduces well control principles and kill sheets before their first well control course.

- Drill and shut in a well on a drilling simulator
- Complete the IWCF kill sheet for surface and subsea kill operations
- Use the drilling data handbook to obtain tubular data
- Pass a written test with a minimum score of 70%
