Quotation from their homepage:
“Geophysics is used to provide subsurface images. To attain this goal the geophysicist acquires data, called records. The records are then transformed into seismic sections in 2D or 3D. The succession of operations that cause the change from the record space to the final space domain constitutes the seismic processing. At the end of this IFP School tutorial, you will be able to use the Seismic Processing Workshop software (SPW) developed by Parallel Geoscience.”
A top-notch tutorial to refresh your knowledge about seismic processing.
