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.
