  • Seismic exploration
    Patent number: 3956730
    Abstract: A method of seismic exploration employing a plurality of emission sources and at least one receiver, arranged in a common plane, in which the sources emit signals into the medium to be explored, which are received after reflection by the receiver, the emission times anda received signals being recorded and correlated to yield required information, and in which the relative emission times of the pulse sources is determined by a predetermined program. Apparatus for carrying out this method is also proposed.
