Observations of breakouts and drilling-induced tension fractures (DITFs) in two 5 km deep boreholes of the European Enhanced Geothermal Project of Soultz-sous-Forêts, France have been combined with the analysis of pressure data from stimulation tests in all 3 deep wells to obtained a description of the state of stress in the granite down to 5 km depth. The orientation of the maximum horizontal stress, SHmax, in the 5 km deep reservoir is found to be N169°E±14°, in accord with previous results… CONTINUE READING
