A method for acquisition of seismic data from an area surveyed using a group of seismic energy sources and a group of seismic streamer cables, particularly a marine area, includes forming a first group A from at least two elements of either seismic energy sources S or seismic streamer cables C having a spacing X between the elements, forming a second group B from at least two of the other elements of sources S or cables C than that forming group (A), spacing the elements in group B a distance equal to X multiplied by the number of elements in group A, forming a group C from at least two subgroups each consisting of a group A, spacing the subgroups in group C in distance equal to the distance between two elements in group B multiplied by the number of elements in group B, the spacing between two adjacent subgroups being equal to the lateral distance between midpoints between the subgroups, and forming further groups as desired D, E, F etc., by combining at least two subgroups of group B, C, D, respectively, etc., each further group having a lateral spacing between the midpoints between two adjacent subgroups equal to the lateral distance between the midpoints between two adjacent subgroups in group C, D, E, respectively, etc., multiplied by the number of subgroups in groups C, D, E, respectively, etc.
