Drilling Calculations

Course details

To give the professional junior drilling staff the necessary knowledge regarding common formulas and calculations used in the oilfield. Participants are also introduced to well control principles and kill sheets, prior to attending their first well control course.

Objectives

• Understand basic calculations used in well control.
• Drill and shut in well on the Drillsim 5000 simulator.
• Fill in the IWCF kill sheet for surface and subsea kill operations.
• Use the drilling data handbook to obtain various tubular data.
• Obtain sufficient knowledge about the course content to pass a written test with minimum 70% score.

Course agenda
