Velocity Centric Modeling

Paradigm fully integrated velocity model-centric applications enable geoscientists working with Paradigm® GeoDepth® to use the advanced structural and stratigraphic model building capabilities of SKUA-GOCAD™ in the depth imaging workflow.  This capability is particularly valuable in geological regimes defined by faults, salt bodies, unconformities, etc.
