Casing & Tubing Design (Advanced)

Advanced well engineering course that introduces HPHT casing and tubing stress analysis to senior well engineers, comprehensively covering complex design challenges presented by HPHT & uHPHT environments. The course provides insights to balanced well integrity and best well architecture configurations using WellCAT hands-on training.
