Methodologies and techniques of processing of deep multichannel seismic data in the Gulf of Naples (Southern Italy)

摘要

The techniques and methodologies of seismic data processing applied to deep multichannel seismic data recorded in the Gulf of Naples are herein shown and presented. The processing techniques used for the elaboration of the seismic profiles are up-to-date and some of them are based on complex mathematical models, which have allowed to carry out a good attenuation of multiples (especially the sea bottom multiples) and to perform good velocity analyses for the production of the stacked sections, on which the geological interpretation has been carried out. The procedures of treatment of the multichannel seismic data starting from the field data are reported in sketch diagrams of data elaboration applied to the different phases of the whole data processing. The used software are the Promax 2D (Landmark Ltd) and the Seismic Unix (Colorado School of Mines). The predictive deconvolution and the spiking deconvolution have been applied to three processed seismic profiles. The best results have been obtained through the application of the spiking deconvolution, allowing for a simple definition of the different seismic reflectors during the geologic interpretation of the processed lines.
