1. A method of seismic data processing the method comprising:
acquiring undersampled seismic data from one or more sources and one or more receivers of a seismic survey with a non-uniform sampling grid designed using non-uniform optimal sampling design, the non-uniform sampling grid including at least one of the one or more sources or the one or more receivers positioned with a non-uniform spacing;
modeling near-angle water bottom reflection data;
attenuating multiples from the undersampled seismic data; and
generating a seismic image of reservoir structures.
