  • Wavelet transform method for downward continuation in seismic data migration
    Patent number: 5392255
    Abstract: A depth migration method for seismic data involves a depth migration in the omega-x domain with an added transform in the wavelet domain. The input to the migration is one spike at a given time and x position (or Common Depth Point). This is as if instead of using a collection of seismic traces as input to the processing sequence, traces are used which would be all null except one which contains a spike. The processing sequence involved for seismic traces is the same as the one involved for the spike (or impulse). The only difference is the input itself being the seismic trace rather than the impulse spike.
