What is the Advanced HPHT Well Engineering training course objective?

The objectives of this course are to provide the participants with an understanding of the complexities associated with HPHT well design and associated drilling operations. All the topics in this course relate to high pressures and high temperatures. It is assumed that participants understand conventional well design and drilling operations. At the end of the course, the participants will understand and be competent in:

• Narrow Drilling Margins and effects on Kick Tolerance
• Predictions of Pore pressures and the challenges
• The impact of both high pressures and temperatures and significant changes in temperatures on the observed behavior of the well
• Understand the impact of temperatures and pressures on primary and secondary well barriers
• Well-design requirements for HPHT
• Understand Operational Planning and Operational Challenges associated with HPHT
• Rig equipment requirements 
• Understand Well Delivery, fingerprinting, well bore breathing, and high-reliability drilling practices  
• Well Control – practical well control for on-bottom, off-the-bottom, and out-of-whole well control, kicks, and losses
