Noise attenuation of multiple source seismic data

A system comprising:

• a processor;
• memory operatively coupled to the processor;
• and
• processor-executable instructions stored in the memory to instruct the system to:
• acquire seismic data of a seismic survey of a region of the Earth that utilizes multiple seismic energy sources and seismic energy receivers wherein the seismic data comprise blended seismic data for a number of emissions from a corresponding number of the multiple seismic energy sources;
• determine spatially distributed coherent noise properties for the region using the blended seismic data, wherein the spatially distributed coherent noise properties comprise phase velocities;
• using the spatially distributed coherent noise properties, model coherent noise as at least two coherent noise models for at least two of the emissions from a corresponding at least two of the multiple seismic energy sources;
• using the coherent noise models, attenuate coherent noise in at least a portion of the blended seismic data to generate coherent noise attenuated blended seismic data;
• deblend the coherent noise attenuated blended seismic data to generate deblended seismic data;
• and
• render an image of at least a portion of the region of the Earth to a display using the deblended seismic data.
