Operational Drilling Technology

Operational Drilling Technology (ODT) Course

This program is developed to teach drilling practices and problems from Spud to completion for all levels from assistant driller to drilling manager. The course is taught by hole intervals starting with top-hole problems related to big-hole and normal pressure. After an appropriate casing string has been set, drilling continues into the abnormal pressure zone and heavy mud practices and problems are discussed. Well Control is introduced as one of the drilling problems and is taught by hole interval, actual case studies and enhanced training by hands-on simulator practice.
