Deconvolution of Surface Seismic Data Using Vertical Seismic Profiles
, by Ronald F. Ullman
Two major objectives of surface seismic data processing are collapsing the seismic source waveform into a spike and removing multiple events. The first objective, deconvolution, requires the shape of the source waveform. The second objective, de-reverberation, requires information about the position of the multiples. The source waveform's shape and the position of the multiples is not readily available from surface seismic data. A vertical seismic profile near the location of the seismic survey can provide an approximation of the source waveform and the location of the multiples. This information is available from vertical seismic profiles because dip filters are able to separate upgoing and downgoing waves. Once an algorithm extracts the source waveform and multiple information from the vertical seismic profile, processing algorithms can use the information and deconvolve the surface seismic section.
