Abstract

Jian, X. and Zhu, S., 2015. Predictive deconvolution for attenuation of multiple reflections in marine seismic data processing.

For reverberation, interlay multiples, and other short-period multiples commonly seen in seas, predictive deconvolution of multiple attenuation is not very effective. In this paper, adaptive predictive deconvolution is proposed through which the prediction step and factor length can be automatically set by the distribution cycle and scope of different multiples. Model comparisons showed that the new method has obvious advantages in processing interlayer multiples with high energy and ambiguous wave-group characteristics and is verified by real data. Some key resulting maps are analyzed and compared. This method has good potential.
