Abstract: Method, source array and seismic vibro-acoustic source element for seismic data acquisition. The number of beams of acoustic energy to be generated for the seismic data acquisition are determined or selected. A different pilot signal is generated for each of the number of beams of acoustic energy. A plurality of drive signals are generated using the different pilot signals. An array of source elements are driven using the plurality of drive signals to generate the two or more beams of acoustic energy.

Abstract: 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.
