Abstract

The seismic recordings comprises number (n) of traces, each provided by a receiver. A constant correction velocity (V) is applied to each trace, then corrected traces are summed, and this operation is repeated X times, correction velocities within a range V1 to VX being applied successively so that X groups of n corrected traces are obtained. These are then summed. The computation process includes determination of the range of variability of the propagation velocities V always within the range 500 to 700 M/secs. The range is subdivided into X different velocities V1 to Vx.
