Drilling Engineering and Operations Course
Introduction:
This course offers a comprehensive introduction to the drilling process, covering everything from the initial spud to the final well completion. It is an intensive training program that is widely recognized as the most comprehensive drilling course available in the industry.
Course Objectives:
This course offers a practical approach to well design and drilling operations. On completion of the course, participants will be able to plan and design most wells whether vertical, directional or horizontal. Participants will also be able to write drilling programs and understand whole problems.
Who Should Attend?
This course is aimed at drilling engineers.
