ABSTRACT A Process and an Apparatus for Seismic Geophysics with Processing by Focuses The invention relates to seismic prospecting of the sub-surface. At least two adjacent focuses F and F', at least one reflecting interface H and directions such as (D1) and (D2) are selected in the sub-surface. A seismic trace, from which a portion containing the effect due to the reflecting interval is extracted, is made to correspond to each direction and to each focus. The correlation function between the two trace portions relative to two adjacent focuses and the same direction is then determined. The correlation functions obtained are finally summed for the different directions. Application to high resolution seismic prospecting.
