Abstract

A method for seismic surveying includes towing a first seismic energy source in a body of water and a second seismic energy source at a selected distance from the first seismic energy source. The first seismic energy source and the second seismic energy source are actuated in a plurality of firing sequences. Each of the firing sequences includes firing the first source and the second source. Signals generated by a seismic sensor system deployed on the bottom of the body of water in a selected pattern are recorded. A time interval between firing the first source and the second source is varied between successive ones of the firing sequences. The times of firing the first and second source indexed so as to enable separate identification of seismic events originating from the first source and seismic events originating from the second source in detected seismic signals.
