Conclusions

By framing the shot-profile migration imaging condition as a 2-D deconvolution in the (xs,t) plane the final image resolution is enhanced. The 2-D deconvolution gives better resolution than the crosscorrelation and the 1-D deconvolution imaging conditions.

The 2-D deconvolution imaging condition gives also a more robust result than the 1-D deconvolution imaging condition because it is less dependent on the regularization parameter and it is less affected by the low frequency noise. This is an important property of the 2-D deconvolution, since one deconvolution application major handicap is the selection of the regularization parameter.

In addition, the angle-domain CIGs computed with the 2-D deconvolution imaging condition are less affected by low resolution effects. Consequently, we can estimate better velocities with migration-focusing velocity analysis.
