METHOD AND APPARATUS FOR PROCESSING SEISMOGRAHIC DATA BY CORRELATION

The invention relates to a method and apparatus for processing data from a seismic survey. In accordance with the invention, the data is regrouped to form a plurality of seismic images (A1, A2, A3, B1, B2, B3, C1, C2, C3). These images being defined by image elements defined in spatial position with respect to an operation direction (D) and having a grey level of predetermined amplitude, the method consisting for each pair of images (Ai,Bj) of carrying out processing by correlation of the amplitude of the grey levels, in order to establish an intercorrelation coefficient and to compensate the localization errors in the position of the images. Application to mono-, bi- or tri-dimensional marine geophysical prospecting.
