The microseismic network in operation during the 1995 stimulation, injection and circulation experiments represents a slightly modified version of the 1993 system. It consisted of accelerometers (4-component sensors) built by the CSMA in boreholes 4550, 4601, 4616 and of a single hydrophone in EPS1. These sensors were used throughout the 1995 experimental programme. A further hydrophone was deployed in GPK1 at a depth of 3480m to monitor the brine injection (Wilson, S.A., Jupe, A.J., Jones R.H. and Dyer, B., 1996.Microseismic results from the 1995 Soultz experimental programme, CSMA Report for Socomine, January 1996.). The X,Y,Z coordinates in the file refer to the local coordinate system with the GPK1 wellhead as origin: X: Easting in meters from GPK1 wellhead (toward magnetic East) Y: Northing in meters from GPK1 wellhead (toward magnetic North) Z: Depth in meters from GPK1 wellhead The local coordinate system is based on the UTM32 system. The coordinates of the stations in the local coordinate system have been obtained from the thesis of S. Bourouis (Sismicité induite et comportement mécanique d'un massif granitique fracturé par injection d'eau). The exact coordinates of the GPK1 hydrophone have not been retrieved and so are not in the file. The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system. Last update of data: 24/07/2019

After drilling GPK2 an extensive hydraulic program was performed in 1995 to test the well and the circulation with GPK1. The main tests were realized during June, July and August 1995. It consisted first of two injection tests at GPK2 in June. The injection tests revealed that the injectivity was too low to consider circulation between the two wells GPK1 and GPK2. A short term and a long term stimulation experiments were also performed in June at GPK2 to stimulate the fracture network. A total of 28000 m3 of fluid was injected during the long term experiment. Following the stimulations, a stepped post-fracturing injection test was realized to observe the results of the stimulations. Finally, three relatively short circulation experiments were performed in July and August by using GPK1 as production borehole and GPK2 as reinjection borehole. Dates of the different tests of the 1995 hydraulic programme: - First injection test at GPK2: from 11:26 11/06/95 to 01:50 12/06/95 - Second injection test at GPK2: from 11:56 12/06/95 to 23:11 12/06/95 - Short term stimulation experiment at GPK2: from 20:00 14/06/95 to 01:27 15/06/95 - Long term stimulation experiment at GPK2: from 10:24 17/06/95 to 16:03 28/06/95 - Stepped post-fracturing injection test at GPK2: from 08:08 01/07/95 to 20:02 02/07/95 - First circulation test between GPK1 and GPK2: from 08:35 09/07/95 to 21:32 24/07/95 - Second circulation test between GPK1 and GPK2: from 13:09 31/07/95 to 19:04 09/08/95 - Third circulation test between GPK1 and GPK2: from 04:50 16/08/95 to 19:19 20/08/95 Baumgärtner, J., Jung, R., Gérard, A., Baria, R. and Garnish, J., 1996.The European HDR project at Soultz-sous-Forêts: stimulation of the second deep well and first circulation experiments, Proceedings of the 21st Workshop on Geothermal Reservoir Engineering, Stanford University, Stanford, California, January 22-24, 1996.

A series of hydraulic tests were performed from August to October 1996 at the GPK2 well (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK2). First a production test was conducted in August to determine the productivity of the well. The production test was followed by a second stimulation of GPK2 after the previous one in 1995. The open hole section of the well was re-stimulated at flowrates up to 78 l/s. A total of 28000 m3 of fluid was injected during the test. The stimulation was followed by a stepped injection test to determine the injectivity of the well after the stimulation. Finally, two circulation tests during which the water produced from GPK2 was reinjected in GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1) were performed in October 1996. About 7500 microseismic events were detected during the experiments, and about 5700 were located. Dates of the different tests of the 1996 hydraulic programme: - Production test at GPK2: from 09:20 14/08/96 to 03:40 15/08/96 - Stimulation test at GPK2: from 16:30 18/09/96 to 22:15 25/09/96 - Stepped injection test at GPK2: from 10:30 29/09/96 to 04:00 06/10/96 - First circulation test between GPK2 and GPK1: from 10:04 12/10/96 to 12:09 20/10/96 - Second circulation test between GPK2 and GPK1: from 15:30 28/10/96 to 19:10 30/10/96 The Episode contains the following datasets: - Microseismic downhole network - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Downhole_network); - Microseismic catalogue with moment magnitude of the downhole network from CSMA - Soultz-sous-Forêts 1996 Stimulation (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Catalogue) - Microseismic catalogue with seismic moment and moment magnitude from Drif et al.(2024) - Soultz-sous-Forêts 1996 Stimulation (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Catalogue_Drif); - Catalogue with hydraulic data from Drif et al.(2024)- Soultz-sous-Forêts 1996 Stimulation (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Seismic_Hydraulic_Comparaison_Drif); - Flow logs - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Flow_logs); - Temperature logs - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Temperature_logs); - Hydraulic data - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1996-Hydraulic);

Microseismic catalogue with local magnitude of the 2000 episode at Soultz-sous-Forêts calculated by B. Dyer (Semore Seismic) using the surface network. Number of events: 51. Microseismic monitoring of the hydraulic programme at Soultz took place between June 30th and July 18th. The catalogue contains the 51 largest events detected on the surface network during the 2000 episode. Each event identity and location in the catalogue was assigned by correlating the times of the events on the surface network with the times of the microseismic events from the catalogue of the downhole network of B. Dyer (available https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-catalogue_downhole). Some discrepancies of few minutes for a same event between the two catalogues are possible because of the gap in time between the twok clocks on the two data acquisition systems. Some locations are missing because of insufficient picks, due to noise, or insufficient data, due to one or more sensors being inoperative. Time period: 30/06/2000 23:09 - 25/07/2000 09:06 (UTC time). The data parameters are the following: Column 1: Event number Column 2: Date (UTC) Column 3: Time (UTC) Column 4: Easting from GPK1 wellhead * Column 5: Northing from GPK1 wellhead * Column 6: Depth from GPK1 wellhead * Column 7: Latitude WGS84 ** Column 8: Longitude WGS84 ** Column 9: Elevation WGS84 ** Column 10: Local magnitude * The local coordinate system is based on the UTM32 system. ** Latitude, longitude and elevation have been derived from the local coordinate system. The description of the surface network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-surface_network). The velocity model used is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-velocity_model_downhole). Last update of data: 20/01/2022
