Multichannel deconvolution imaging condition for shot-profile migration

ABSTRACT

A significant improvement of seismic image resolution is obtained by framing the shot-profile migration imaging condition as a 2-D deconvolution in the shot position/time (xs,t) domain. This imaging condition gives a better image resolution than the crosscorrelation imaging condition and is more stable than the ``more conventional'' 1-D deconvolution imaging condition. A resolution increment is also observed in common image gathers (CIGs) computed with the 2-D deconvolution imaging condition, thus allowing a more accurate velocity analysis.
