Improving Underlying Image by Resolving High Velocity Anomaly Using Sonic Log in Velocity Model Building
In the presence of complex geology and lateral velocity variations, unresolved velocity anomalies in the overburden degrade deeper imaging.
This paper shows how an improved subsurface image was achieved below an anomalous high-velocity zone using anisotropic Kirchhoff PSDM.

The Aspen GeoDepth velocity determination and 3D/2D velocity model building system enables explorationists to perform accurate seismic imaging in either time or depth. Through the integration of interpretation, velocity analysis, model building, time-to-depth conversion, depth migrations and model verification and updating, Aspen GeoDepth provides the continuity needed to produce high-quality, interpretable images consistent with other available data, while preventing data loss and honoring geologic constraints.
