Preparation
• Installation of seismic monitoring network
• Recording of existing cracks in sensitive buildings
• Construction of the drill pad
Exploration drilling
First exploration well down to a final depth of approx. 4000m
Measurements, tests and updating of the risk assessment study
Measurements in the borehole and complementary geophysical measurements on the surface
• Hydraulic tests to characterize the reservoir rock
• Updating of the risk assessment study
• Review and modification of the implementation concept
Second deep drilling and main stimulation
• Second drilling down to the final
depth and horizontal section
• Multi-stage stimulation of the
reservoir
Closing of the circulation loop
• Drilling of the horizontal section
of the first borehole
• Potential stimulation of the first
borehole
• Circulation test between the
boreholes
Construction of the power plant
• Construction of the surface installation and of the building
• Connection to the power grid
Commissioning, trial run and regular operation
• Commissioning of the power
plant
• Measurements and
optimization of the plant
• If possible, connection to the
district heating network
