Deghosting benefits traditional seismic processing and is a prerequisite to all inverse-
scattering-series based processing. The freedom of choosing a convenient reference …

We evaluated a solution to seismic deghosting that deghosts the low-frequency components
of the seismic pressure data. In an approximation that neglected the dependence on …

Methods for wavefield injection are used in, for instance, reverse time extrapolation of shot
gathers in reverse time migration. For correct injection of recorded data without any …

A new Green's theorem deghosting algorithm is developed, analyzed and tested. The
deghosting algorithm requires both pressure and its vertical derivative on the measurement …

As one of the pre-requisites for multiple removal, imaging and inversion, the effectiveness of
deghosting affects the performance of the followed operations. Extinction Theorem based …

In recent years, significant advancements have been made in deep-sea broadband seismic
acquisition and its support data processing technologies. Compared with traditional constant …

Depth imaging of seismic reflection data plays an fimportant role in discovering oil and gas
reservoirs as well as in characterizing and defining the extent of previously discovered …

摘要作为一种特殊的噪声, 鬼波对一次波的波形及频带宽度产生极大的影响,
鬼波压制是提高海上地震资料分辨率及保真度的重要因素. 以格林公式为基础 …

In seismic exploration, acquiring full surface coverage with point receiver data is generally
consistent with wave theoretic processing requirements. It is important to characterize the …

We have developed a new and simple method for deghosting of conventional hydrophone
streamer data towed at arbitrary variable depths. The method uses a time-space domain …
