Patent number: 9759827Abstract: Method for generating an excitation signal for a first vibratory seismic source so that the first vibratory seismic source is driven with no listening time. The method includes a step of determining a first target spectrum for the first vibratory seismic source; a step of setting a first group of constraints for the first vibratory seismic source; and a step of generating a first excitation signal for the first vibratory seismic source based on the first group of constraints and the first target spectrum. The first seismic traces recorded with plural receivers can be identified when the first vibratory seismic source is driven with no listening time, based on the first excitation signal.Type: GrantFiled: December 11, 2013Date of Patent: September 12, 2017Assignee: CGG SERVICES SASInventors: John Sallas, Robert Dowle, Laurent Ruet, Benoit Teyssandier
