Seismic surveys in shallow water areas and in transit zones are carried out using bottom three-component recording devices due to objective restrictions on operations with towed streamers and to simultaneously receive information on exchange transverse waves for the subsequent solution of a wide range of tasks for describing reservoirs and determining their anisotropic properties. The design of such works for 3D is mainly aimed at optimizing spatial observing systems, taking into account the significant advantages of the sea source in terms of performance compared to the work on the location and movement of receiving sensors on the seabed. In such cases, optimization consists in locating the receiving arrangement on as large area as possible with increased distances between registration points (RP) and the array moves in its entirety, over the entire area of the arrangement, without overlaps along the RP. The distribution of the distances and azimuths in the CDP bins and with fold increase over the overlaps are regulated only by a multiple decrease in the distance between the SP and the SP overlaps along the explosion lines according to the principle of reciprocity.
