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.

Unique advantages of Paradigm velocity modeling solutions
Velocity determination and modeling for all regimes – subsalt, shales, fractured carbonate, overthrust, overpressured, stratigraphic
