Course description
Deepwater Well Engineering - DWE
This is a five-day course designed to promote understanding of well design and engineering capabilities unique to the deep water environment. Participants are actively engaged in the skills and activities required to deliver a cost-effective well plan, while also gaining valuable perspective on the role of a DW drilling engineer as a project manager. Suggested course prerequisites include 3+ years' experience in drilling and 2+ years in a well planning role for onshore or shallow water applications.
"Overall a very good course. Instructor was very insightful." - Vice President Engineering, United States
"I really enjoy the teaching approach. Also I really enjoyed the practical teamwork." - Well Operations Engineer, Canada
Suitability - Who should attend?
Experienced drilling engineers, drilling supervisors, and other petroleum professionals that are new to deep water (DW) who will become involved or responsible for DW well planning or oversight of non-operated DW wells. The ten day, Well Design and Engineering (WDE) course, or its equivalent, is highly recommended as a pre-requisite.
