M ultiple removal is a longstanding problem in exploration seismology. Although methods
for removing multiples have advanced and have become more effective, the concomitant …

Almost every link in the chain of exploration seismology methods used to process recorded
data has been affected by Green's theorem. Among the seismic processes that can be …

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

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 the direct nonlinear inversion method and in algorithms for 1D elastic media, P-wave
velocity, S-wave velocity, and density are depth dependent.“Direct nonlinear” means that the …

Deghosting is one of the most important factors for enhancing resolution and higher fidelity
in marine seismic exploration. Inverse scattering theory and a deghosting method based on …
