Velocity model used by M. Calò and C. Dorbath. The velocity was derived from sonic logs operated by Schlumberger in GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1) and from transit times for shots fired inside GPK1 at different levels and recorded on the IMRG downhole network (Beauce et al., 1991). The catalogue of events located during 2003 stimulation using the downhole and the surface network is available here (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2003-catalogue).

Microseismic catalogue of the 2003 episode at Soultz-sous-Forêts calculated by B.C. Dyer, R. Baria and S. Michelet using the downhole network. Number of events: 21979. The catalogue covers the five phases of the 2003 hydraulic program. Seismic monitoring continued several days after the circulation test. Events were located by a combination of automatic and manual processing methods. Only events that could be located with an RMS misfit < 15 ms were accepted in the catalogue. Time period: 27/05/2003 16:10:29 - 28/07/2003 04:06:26 (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 ** * 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.

Microseismic catalogue of the 2003 episode at Soultz-sous-Forêts calculated by M. Calò and C. Dorbath using the surface network. Number of events: 4728. The catalogue was used to perform a time-dependent (4-D) seismic tomography. It covers all the five phases of the 2003 experiment program. The location of events was performed using an automatic procedure for detecting and picking the seismic phases. About 7500 triggers were detected and 4728 events were finally located using at least eight P- and three S-arrival times with a root mean square (rms) lower than 0.04 s.

The 2010 circulation test began in November 2009 after a maintenance period and lasted until October 2010, when a new maintenance period was programmed. This 11-month experiment is the longest circulation ever performed on the Soultz project. During the test, GPK2 was used as production well (with Line Shaft Pump), GPK3 and GPK1 as reinjection wells (Cuenot, N., Genter, A., 2015. Microseismic Activity Induced During Recent Circulation Tests at the Soultz-sous-Forêts EGS Power Plant). The Episode contains several datasets which you can find further down the page in "Links".
