Claim Text:
1. A method to determine structural information about a geological subsurface, the method comprising: using a programmable computer to perform the following: separating dual-sensor seismic data into aliased and unaliased parts in a frequency-wavenumber domain; processing the seismic data in the unaliased part using a conventional vertical wavenumber; processing the seismic data in the aliased part using an alternative vertical wavenumber additionally based on a Nyquist wavenumber for the seismic data; combining the processed unaliased seismic data and the processed aliased seismic data; and generating an image of the geological subsurface using at least in part the combined processed unaliased and aliased seismic data, the image revealing structural information about the geological subsurface.
