Zero-Azimuth 3D Surface Multiple Prediction (SMP)

Zero-azimuth 3D SMP is a highly efficient implementation of 3D SRME, using the industry standard zero-azimuth assumption. It is particularly suitable for narrow-azimuth towed-streamer acquisition techniques. Irregular or sparse input data is regularized and interpolated on-the-fly using unique WesternGeco technology.

The 3D raypath of the multiples is captured by the formation and stacking of crossline Multiple Contribution Gathers (MCGs). This technique significantly improves the attenuation of complex multiples compared to 2D SRME, and has been explicitly parallelized for cluster computing in order to ensure consistently high-quality results, and rapid turnaround.
