Corrosion Testing for Hot Dry Rock Geothermal Wells in Soultz-sous Forêts-Preliminary Results
 
Corrosion risk for some materials proposed for Soultz 
project at 200°C was evaluated for different steels with 
and without protective coating. The preliminary 
experiments were performed at autoclave which could 
house specimen of various geometries and which 
allowed electrochemical measurements. In some cases 
the testing was performed using a corrosion 
inhibitor. For uncoated steels the corrosion tests 
showed erosion at 2 mm/y at 200°C.  The corrosion 
products formed on the surface did not provide any 
corrosion protection. All the tested coatings performed 
very well. They effectively reduced the corrosion and 
they did not deteriorate during the test. 
The chosen inhibitor did not give any significant inhibitor 
effect.
