Abstract
In a method of acquiring seismic data in a prospecting area, an array of excitation vibration receivers is placed on or over the terrestrial surface. A plurality of excitation vibration sources is disposed in the vicinity of the array, each source emitting excitation vibrations with a frequency spectrum in a specific frequency band. These bands are adjacent and together cover the frequency band of usable seismic data signals. When the excitation vibrations are emitted by the plurality of sources, the excitation vibration echoes reflected from strata beneath the terrestrial surface are registered by the receivers. The above steps are repeated for a plurality of successive trace increment displacements to produce an emission figure and to cover the prospecting area. The method and the device implementing it can be used for acquisition of terrestrial or marine seismic data.
