ABSTRACT:
A 3-D seismic prospecting method is provided which employs an areal array of sources and receivers by which seismic traces are generated. The areal array is segregated into a plurality of shells and angularly separted sections from which a preselected number n.sub.1 of source-receiver pairs are selected for a particular common midpoint. By means of the shells and sections, the source-receiver pairs so selected have associated therewith a wide range of offsets and azimuth angles for the preselected fold n.sub.1. The seismic traces corresponding to the selected source-receiver pairs are summed to give a stacked trace corresponding to the common midpoint.
