SKUA-GOCAD - Velocity Modeling and Calibration Using SKUA

In this flexible one to two-day course the student learns how to make the most of the unique SKUA technology to build geologically constrained velocity models and perform efficient time-to-depth conversion. Unlike other solutions where structural complexity is a limiting factor, SKUA structural and stratigraphic modeling enables accurate time-to depth conversion in salt and structurally complex environments, and provides all the tools needed to create geologically realistic velocity models.
