5-Day Deepwater Well Design and Operational Practices
Session Details
Agenda
K&M’s newest course focusing on identifying and overcoming deepwater well construction challenges! This course is a comprehensive well design and implementation event for Wells Engineers, Superintendents, and Wells Managers. Learn how to identify risks in deepwater well design for both Drilling and Completions and utilize fit for purpose operational practices to increase efficiency and reduce NPT.
