3D SRME

Advanced Demultiple for Wide-Azimuth Data

CGG’ true-azimuth 3D SRME provides highly effective multiple attenuation for any acquisition geometry.

Our complementary data-driven and wave-equation modelling techniques respect the true offset and azimuth of the traces and can be applied directly to wide-azimuth data. The additional cross-line offsets which wide-azimuth data provide allow the generation of a more accurate multiple model which results in more effective multiple attenuation and better preservation of primaries.

FEATURES

  • 3D 'True-azimuth' SRME
  • Wide-azimuth data improves 3D SRME accuracy
  • Can be applied directly to wide-azimuth data:
    • Wide-azimuth towed streamer
    • OBS/OBC
