Abstract
The successful circulation test carried out at Soultz in 1997 demonstrated that it is possible to circulate at flow rates of around 90 tons/h between two wells with a separation of 450 m and in the depth range of 3000 - 3500 m. However, the future industrial deployment of the HDR technology developed at Soultz requires that the past experiments be replicated at higher temperatures and larger flow rates in order to further improve the efficiency and economy of the technology. Consequently, it was decided to extend the investigations down to 5,000 m. At this depth temperatures of around 200?C were anticipated.
