Heffring, Calgary, Alberta, Canada, assignor to Esso Production Research Company, a corporation of Delaware Filed Oct. 12, 1966, Ser. No. 586,075 7 Claims. (CI. 340—) Ringing events are eliminated from a trace of a re- producible seismogram taken at marine locations by ad- justably attenuating electrical signals produced from a trace, delaying the trace by an amount equal to the seis- mic wave travel time through the water layer beneath the source, and adding the original signal to the unde- layed and unattenuated signal. This process is repeated using a delay equal to the travel time of waves in the water layer beneath the seismic wave detector. The ap- propriate attenuation and time delay is determined by autocorrelation of traces produced by vertically traveling seismic waves at the ends of a geophone spread.
