Abstract
A method of seismic exploration using acoustic logging comprises transmitting and receiving sound waves, recording all of the signals received by the receivers, the respective positions of the emitter-receiver pair which give rise to each recording, grouping the recordings in pairs so that each recording of a given pair of sound paths have a common path segment and a part which is not common to both which is located facing the geological stratum of interest and the difference in time of arrival for at least one type of wave is measured for each pair.
