Abstract: Methods related to controlling a source array while performing a seismic survey to achieve an intended source signature. A current three dimensional arrangement of the individual seismic sources is compared with a target 3D arrangement. In view of the comparison, position of at least one of the individual seismic sources is adjusted so that the adjusted 3D arrangement of the individual seismic sources to substantially match the target 3D arrangement.

Abstract: Method and streamer/source head-float system for connecting to a head portion of a streamer or to a lead-in or providing information about a source. The system includes a head-buoy configured to float in water and connected through a cable to the head portion of the streamer or to the lead-in; a head-float configured to float in water; a connector connecting the head-float to the head-buoy; and positioning equipment attached to the head-float and configured to determine a position of the streamer or the source.

Abstract: System, medium and method for de-blending seismic data. The method for acquiring blended seismic data associated with a subsurface of the earth includes receiving coordinates of a sail line associated with first and second shot point locations; towing first and second source arrays in water along the sail line; shooting the first and second source arrays with a constant delay parameter so that a seismic trace recorded by a seismic sensor has at least a first uncontaminated portion that includes seismic energy generated substantially only by one of the first and second source arrays and a second portion that includes seismic energy generated by both the first and second source arrays; and recording blended seismic data generated by the first and second source arrays with the seismic sensor.
