1. A method for exploring structure of an underground formation, the method comprising: acquiring seismic data using a seismic source that injects seismic excitations into the underground formation, and receivers that generate the seismic data based on detecting seismic excitations emerging from the underground formation; receiving, by an interface, the seismic data; separating, by a processor, the seismic data into a fine-scale dataset and a coarse-scale dataset wherein each dataset includes a non-zero portion of the seismic data, so as the coarse-scale dataset carries information about a layer structure of the underground formation, and the fine-scale dataset preserves information about fine-scale features of the underground formation; applying, by the processor, a five dimensional (5D) interpolation to the coarse-scale dataset which results in an interpolated coarse-scale dataset; applying, by the processor, one of a three dimensional (3D), a four dimensional (4D) or a 5D interpolation to the fine-scale dataset which results in an interpolated fine-scale dataset; summing together, by the processor, the interpolated coarse-scale dataset and the interpolated fine-scale dataset which results in a summed interpolated dataset; regularizing and preparing, by the processor, the summed interpolated dataset for prestack migration; and displaying, by a display, at least one image of the structure of the underground formation based on the summed interpolated dataset, the image enabling an evaluation of presence or absence of hydrocarbon deposits in the underground structure.
