N2  - A team of Japanese researchers, with long experience in
passive seismic monitoring in the area of development of hot
dry rock (HDR) and hot wet rock (HWR) geothermal
systems, carried out seismic monitoring at the Australian
HDR site being developed by Geodynamics Limited in the
Cooper Basin. The seismic network consisting of 4
near-surface stations and 4 downhole stations detected
approximately 32,000 triggers during injection of 20,000 m3
of liquid into granitic basement over 3 weeks. The authors
located the events on a semi-realtime basis and the locations
were fed back to the pumping side. The locations of seismic
events showed sub-horizontal extension of the reservoir to
1,800 m away from the injection well at a depth of around
4,500 m. The heterogeneous source migration suggest that
the reservoir was close to a critically stressed state.
