Simultaneous Reorientation and Redatuming of Very High Resolution Seismic Recordings in Shallow Water Surveys

We consider the challenges associated with very high resolution (VHR) seismic profiling of near-seafloor sediments, within shallow-water environments. Specifically we introduce a method for correcting for the effects of these challenges (temporal variations in water-column velocity—depth structure and source-receiver geometry changes linked to sea-state fluctuations) during data-processing. By using numerical-modelling in a V(Z) sense, seismic reflection data are slant-stack transformed to tau-p, primarily in order to retain surface-consistency for subsequent signal processing.
