Specialised Technical Workshop
Uncertainty Analysis and Optimization – Advanced Workshop(SEG Standard Course)
Develop a structured approach to uncertainty analysis, sensitivity review and optimisation choices in subsurface studies.
Course Overview
Examines how uncertainty affects technical decisions and optimisation choices. Participants compare assumptions, sensitivity results and alternative scenarios when evaluating exploration and subsurface problems.
