Classification: CPC G  B | IPC B  G

Claim 16:
17. A method for manufacturing a geophysical data product, the method comprising:
generating coded pseudo-random signals for driving the marine vibrators based on coded pseudo-random sequences;
using the coded pseudo-random signals to activate the marine vibrators to generate orthogonal coded pseudo-random sweeps that penetrate a subterranean formation located below the body of water;
recording wavefields reflected from the subterranean formation in seismic data generated by receives located in the body of water;
sorting the seismic data into the common-receiver domain to obtain seismic data with incoherent residual noise; and
storing the seismic data in a non-transitory computer readable medium, wherein generating the coded pseudo-random signals for driving the marine vibrators comprises repeatedly using seed binary sequences to generate the coded pseudo-random sequences.
