Abstract
Computing device, computer instructions and method for removing cross-talk noise from seismic data and generating an image of a surveyed subsurface. The method includes receiving input seismic data D generated by firing one or more seismic sources so that source energy is overlapping, and the input seismic data D is recorded with seismic sensors over the subsurface; generating a cross-talk noise model N by replacing at least one original shot gather with a reconstructed shot gather; subtracting the cross-talk noise model N from the input seismic data D to attenuate coherent cross-talk noise to obtain processed seismic data Dp; deblending the processed seismic data Dp with a deblending algorithm to attenuate a residual noise to obtain deblended seismic data Dd; and generating the image of the subsurface based on the deblended seismic data Dd.
