Monitoring boreholes were instrumented with geophones, high-frequency accellerometer, piezoelectric In-situ Acoustic Emission (AE) sensors, AE-accelerometer sensor chains, ultrasonic transmitters, Fiber Bragg Grating (FBG) sensors, fibre optic cables, rod system with centralizers, tiltmeters, pore-pressure sensors and mulitpacker. These instruments will monitor the rock volume during fracture generation and water circulation.
