Microseismic catalogue of the 2005 episode at Soultz-sous-Forêts calculated by B.C. Dyer using the downhole network. Number of events: 3709. The catalogue covers the four phases of the 2005 hydraulic program at GPK4. The events were located by a combination of automatic and manual processing methods. Only events that could be located with an RMS misfit inferior to 5 ms were accepted in the catalogue. Time period: 04/02/2005 01:41:37 - 01/04/2005 18:33:43 (UTC time). The data parameters are the following: Column 1: Event ID Column 2: Experiment phase of the hydraulic program Column 3: Date (UTC) Column 4: Time (UTC) Column 5: Easting from GPK1 wellhead * Column 6: Northing from GPK1 wellhead * Column 7: Depth from GPK1 wellhead * Column 8: Latitude WGS84 ** Column 9: Longitude WGS84 ** Column 10: Elevation WGS84 ** Column 11: RMS Column 12: Local magnitude *** * The local coordinate system is based on the UTM32 system. ** Latitude, longitude and elevation have been derived from easting, northing and depth from GPK1 wellhead. *** The magnitude has been estimated using the relationship derived by Sophie Michelet/Matthieu Darnet based on the peak amplitude at the 4550V sensor: M = (-11 + log10 ((0.85 * PeakAmplitudeAt4550V) / 1.0e-9)) * 1.85.

During February/March 2005 a hydraulic stimulation program was conducted in the well GPK4 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK4) at European Hot Dry Rock Project, Soultz-sous-Forêts, France. It is the second stimulation of GPK4, after the previous one, performed in September 2004. The hydraulic stimulation was followed a few days later by a program of chemical stimulation (injection of diluted HCl). This program involved the chemical stimulation itself and two identical step-rate injection tests. The first injection test was performed before the chemical stimulation and the second after, in order to observe the efficiency of the chemical stimulation. Dates of the 2005 hydraulic programme: - Second hydraulic stimulation of GPK4: from 18:05 07/02/2005 to 18:00 11/02/2005. - First step-rate injection test of GPK4: from 15:30 22/02/2005 to 15:30 25/02/2005. - Chemical stimulation of GPK4 with HCl: from 13:30 02/03/2005 to 06:00 05/03/2005. - Second step-rate injection test of GPK4: from 10:00 13/03/2005 to 09:55 16/03/2005. The Episode contains several datasets which you can find further down the page in "Links".

Microseismic catalogue of the 2000 episode at Soultz-sous-Forêts calculated by B. Dyer (Semore Seismic) using the downhole network. Number of events: 13986. Microseismic monitoring of the hydraulic program at Soultz took place between June 30th and July 18th. During the program, a total of 31511 potential seismic events were recorded from which 13986 seismic events were located.The catalogue covers the two hydraulic tests realized during the 2000 episode. Only the events with an RMS misfit <10 ms were accepted. Time corresponding to the corrected waveforms distributed on the CDGP has been added.

The 2004 stimulation was aimed at improving the hydraulic performances of the well GPK4 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK4). This borehole was stimulated twice. The 2004 episode corresponds to the first stimulation of GPK4. 9300 m3 of water were injected during the test at a constant flowrate of 30 l/s, with peaks up to 45 l/s. A low flow injection test of GPK4 was performed before the stimulation to evaluate the initial injectivity of the well. The data from the injection test are included too. Dates of the 2004 hydraulic programme: - GPK4 low flow injection: from 10:38 08/09/2004 to 10:00 12/09/2004. - GPK4 stimulation: from 08:32 13/09/2004 to 20:00 16/09/2004.
