A 3-D numerical model of the embankment of the railroad was designed to mimic a test field site for which borehole logging data were available.

Twenty-height boreholes have been drilled in a small area of about 18,000 m2 in which borehole loggings and hydraulic tests were carried out to locate the main flowing fractured zones and investigate fractures connectivity.

In particular, we propose a new temperature tomography field method in which borehole temperature profiles are measured under different pumping conditions by changing successively the pumping and observation boreholes.

The methodology was extended to peripheral wells (EPS-1 and 4550) of the Soultz field in which borehole images were available for sediments.

The waste would be emplaced (by remotely controlled or robotic devices) in holes drilled into the floors of these rooms, after which the boreholes would be sealed and the rooms and corridors backfilled.
