The general use of continuous CDP seismic lines means that the neighbourhood of each depth point can be considered according to two sets of co‐ordinates:

— the co‐ordinates of the abscissa on the seismic lines and the reflection time, which allow investigation of the local dip of coherent events;

— the co‐ordinates of the reflection time and the move out, which allow investigations of the average velocity for these same events.

The combination of both investigations for each coherent event is a very convenient operation for the seismologist, and can provide some useful interpretation aids such as velocity profiles, or information on the interval velocities.

The principles which we use consist in the examination of a large range of possibilities, of which only the most coherent are chosen.

Some examples are shown.
