PROCEDE DE TRAITEMENT DE DONNEES SISMIQUES CORRESPONDANT A DES ACQUISITIONS REALISEES SUR UN MILIEU PRESENTANT UNE ANISOTROPIE AZIMUTALE

摘要

The invention provides a method for processing seismic data corresponding to acquisitions from a medium with azimuthal anisotropy. Said method is characterised in that, for two data sets corresponding to at least two different azimuth source/receiver pair spreads, for the same seismic variable and the same area on the ground, an average is determined, for each concerned azimuth, between the data, corresponding to the concerned azimuth and the data, corresponding to a perpendicular azimuth spread, for the same variable and area on the ground, and an estimation of the part which is common to both averaged data sets, thus obtained, is determined.
