Improved Imaging Below the Deccan Trap: An Attempt to See Sub-Trappean Mesozoic Sediments
Sub-basalt imaging is difficult due to loss of seismic energy, attenuation, absorption, scattering and mode conversion.
This paper discusses how reprocessing of vintage 2D lines with improved processing techniques considerably improved image quality.

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.
