Near Surface Geophysics > 3D seismic survey

Usually 3D seismic imaging requires a great amount of data and powerful computer. On the Hydrogeological Experimental Site of the University of Poitiers, a 3D survey has been designed to obtain a 3D cube by recording a low amount of data. The example shows that an optimum choice of signal processing tools ( filters and transformations) allows to process the recorded seismic data to obtain a significant 3D cube in single fold.

The high resolution 3D cube has revealed three high porous, presumably water productive, layers.
