Basic Drilling, Completion and Workover Operation

About The Course

This course provides a technical overview of the science and art of drilling operations, completion practices, post-completion and well intervention. Students will develop understanding of the WHAT, WHY, and HOW of each of these areas of engineering practices.

Who Should Attend

Technical, field, service, support and supervisory personnel desiring to gain an introductory overview of these topics and how they interrelate. Excellent for cross-training of other technical disciplines such as reservoir and surface facility engineers plus geoscientists, and anyone who interacts with drilling, completion or workover design engineers such as technical supervisors and technical service personnel. This is not a fundamental course for training engineers seeking a career in drilling or workovers (for these,PO1 is recommended
