Abstract

It is common practice to record 2D lines with a source and receiver iinterval twice the CDP interval. This presents the double advantage of higher energy and of optimum multiple and radial noise attenuation. In 3D seismic, practival or theoretical schemes are used to define the stacking fold, which as it is much less than a 2D fold, is obtained by low density destribution. Structural requirements, i.e. the anticipated depth and dips of the target, are taken into accoutn in approximately the same way as for 2D seismic in order to define the bin size, shooting distances and migration aperture.
