CPC G01V 1/3808 (2013.01) [G01V 1/3852 (2013.01); G01V 2210/127 (2013.01); G01V 2210/1293 (2013.01); G01V 2210/1423 (2013.01); G01V 2210/1427 (2013.01)] | 18 Claims |
1. A method of seismic data acquisition comprising:
acquiring, with a first seismic source comprising an air gun, a first set of seismic data for a survey area with a first plurality of streamer receivers on a first streamer spread, wherein acquiring the first set of seismic data comprises:
navigating a first propulsion source along a first sail line in the survey area, wherein the first seismic source and the first streamer spread are coupled to the first propulsion source;
activating the first seismic source while navigating the first propulsion source;
while navigating the first propulsion source, navigating a second propulsion source along a second sail line in the survey area, wherein a second seismic source is coupled to the second propulsion source; and
activating the second seismic source while navigating the second propulsion source, wherein the first sail line is orthogonal to the second sail line;
simultaneously acquiring, with the first seismic source, a second set of seismic data for the survey area with a plurality of ocean bottom receivers, wherein the first set of seismic data and the second set of seismic data together form a complete dataset for velocity modeling and imaging; and
simultaneously acquiring a third set of seismic data for the survey area with a second plurality of streamer receivers on a second streamer spread, wherein the second streamer spread is coupled to the second propulsion source.
