Downhole high resolution seismic methods have significant application to geotechnical investigations in rock. A new downhole and crosshole seismic method utilises sophisticated digital acquisition and processing to provide multi-fold subsurface images which show a degree of detail and resolution not attainable previously. Both first and reflected seismic waves are employed in the numerical analysis of the data, which includes beam forming and tube-wave removal. The method shows great potential in geotechnical investigations including the definition of dykes.
