- W4285201468 abstract "Summary Marine vibrators are getting closer to coming to market and with them they bring several advantages. Such advantages include greater waveform control and repeatability, as well having a reduced environmental footprint compared to their airgun counterparts. However, they suffer from one issue that an airgun source does not: the Doppler shift. The Doppler shift occurs due to the movement of marine vibrators during source emission leading to frequency changes in the pilot sweep received at the sensors. To correct the Doppler shift one can either use 2D deconvolution prior to correlation or use an analytical correction either pre or post correlation. An analytical Doppler shift correction for exponential sweeps has been developed and validated on synthetic data. Exponential sweeps are of interest because they can spend more time injecting energy of a lower frequency into the subsurface which may be useful when trying to balance the spectrum at the receiver end. The correction derived requires perfect knowledge of the input waveform as well as the anticipated Doppler shift. This correction is applied in the frequency-wavenumber domain and is shown to work well on common receiver gathers and migrated volumes, assuming no spatial aliasing." @default.
