Z-99 Footprint Suppression with Wavenumber Notch Filtering for Various Acquisition Geometries

It has been shown previously that 3D acquisition footprint can be attenuated either on time slices or on frequency slices by applying a wavenumber notch filter. We have recently experimented with wavenumber domain notch filtering on frequency slices on some commonly used data acquisition geometries from the Middle East and found out that this method can be used with all the geometries we have tested and with data of various geologic
