Abstract
A method and apparatus for surveying a three dimensional sub-surface geological structure having seismic scatterers includes establishing an acquisition system (19) having at least two substantially vertical arrays of sensors (20) disposed within the geological structure. Each array (20) includes multiple directional sensing receivers 30 adapted to receive seismic energy (28, 97) produced from the seismic scatterers (24) in response to at least one seismic disturbance (27). The multiple directional sensing receivers (30) are adapted to provide a measurement of the received seismic energy. A recorder records the measurements of the received seismic energy for producing a complete vector field response of the seismic scatterers to the at least one seismic disturbance. Lastly, a processor processes the complete vector field to generate a three-dimensional image.
