Course Information

The aim of this short course training is to provide a basic knowledge of the theoretical and practical aspects of drilling operations.
 At the end of this course participants will be able to:
• Understand hydrocarbon formation
• Describe key characteristics of hydrocarbon reservoir (rock, source, tap, seal)
• Have idea about upstream and downstream petroleum industry
• Identify different rig types
• Learn different components of drilling rig and understand their basic functions
• Have basic understanding of downhole wellbore pressures and the means to control them
• Learn the principles of drilling, cementing, casing processes
• Learn the principles of well control and blowout prevention
• Understand basic functions of drilling fluids and cement
• List differences between onshore and offshore drilling processes
• Describe the basic principles of logging and MWD/LWD
• Describe the methods of drilling deviated and horizontal wells
• Have an understanding of the components and functions of well completion (valves, artificial lift, sand control)

This short course is intended for all those involved in drilling and requiring basic knowledge of drilling engineering.
