Multiple suppression is a very important step in seismic data processing. To suppress
surface-related multiples, we develop a self-supervised deep neural network method based …

Nowadays, it is more widely accepted that multiple reflections should not be considered as
noise, but as signal that can provide additional illumination of the subsurface. However, one …

海面与海底存在的强波阻抗界面, 导致海洋地震资料中普遍发育多次波与鬼波.
广泛使用的双程波方程有限差分正演方法无法分离不同阶次的多次波及鬼波 …

Abstract The Closed-Loop surface-related multiple elimination (CL-SRME) shares the
common theoretical foundation with traditional surface-related multiple elimination (SRME) …

在油气勘探中, 多次波通常被视为影响地震数据处理和解释结果准确性的相干噪声, 因此,
多次波压制方法研究一直是地球物理勘探领域中的重要研究方向. 鉴于自由表面多次波是地震 …

The strong impedance interfaces of the sea surface and seabed cause significant multiples
and ghost wavefield in marine seismic data. The finite-difference method of the two-way …

Compared with first-order surface-related multiples from marine data, the onshore internal
multiples are weaker and are always combined with a hazy and occasionally strong …

The estimation of the upgoing wavefield based on a ghost model is well-known as receiver
deghosting. The shape of the rough and dynamic (time-varying) sea surface and the varying …

Removal of water‐layer‐related multiples in shallow water remains a challenge due to a
lack of near‐offset data. We have developed a shallow water multiple attenuation approach …

We develop a workflow to invert for primaries from 2D freesurface shallow-water (⇠100m)
data with missing near offsets. The workflow is based on closed-loop surface-related …
