Abstract

Soultz-sous-Forets is the French site of the European Hot Dry Rock (HDR) project of which the objective is the creation of a heat exchanger at depth in the granite that constitutes the basement of the Rhine Graben. Geochemical studies permitted the characterization of the fluid circulation, which occur naturally in the Rhine Graben and are man-induced at
the Soultz site. After the development of the heat exchanger, long- term circulation and tracer tests during the summer of 1997 have allowed for an
improved characterization of the reservoir.
