Conditional Mean Flows for Frequency-Domain Scattered Wavefield Generation
Lipeng Lai, Shaohuan Zu
Frequency-domain wavefield modeling underpins seismic imaging and inversion, where repeated Helmholtz solutions become costly as velocity models, source locations, and frequencies…

Ground roll suppression based on the synchrosqueezed wavelet transform and local adaptive subtraction filtering
Zifei Li, Zhengyu Tan, Shaohuan Zu
Ground roll suppression remains a challenge in land seismic data processing, particularly when strong surface wave energy exhibits significant overlap with effective reflection eve…

Iterative separation of coherent blended signals in common shot gathers using synchrosqueezed curvelet-Radon constraints
Zifei Li, Shaohuan Zu, Haojun Chen
Blended data acquired via simultaneous-source seismic exploration conventionally require post-acquisition deblending, which typically relies on the coherence differences introduced…
