Catalogue of microseismicity with moment magnitude recorded at Soultz-sous-Forêts during 1994 production and injection tests. Calculated by the CSMA. Number of events: 150. Time period: 00:30:36 17/06/1994 to 00:42:02 27/06/1994. The data parameters are the following: Column 1: Seismic ID Column 2: Easting from GPK1 wellhead * Column 3: Northing from GPK1 wellhead * Column 4: Depth from GPK1 wellhead * Column 5: Latitude WGS84 ** Column 6: Longitude WGS84 ** Column 7: Elevation WGS84 ** Column 8: Maximum peak to peak P-wave amplitude Column 9: Maximum peak to peak S-wave amplitude Column 10: Source radius Column 11: Stress drop Column 12: Moment magnitude Column 13: Date Column 14: Time 143 events from this catalogue are in the other microseismic catalogue of 1994 (available https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Catalogue_all) as well. There are differences of location for 26 events between the two catalogues, probably due to the use of different models for the relocation. * 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 microseismic network in operation during the 1994 circulation was essentially the same as that used in the 1993 experimental programme. It consisted of three accelerometers (4-component sensors) built by the CSMA in boreholes 4550 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4550), 4601, 4616 and a single hydrophone in EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1) (Baria, R., 1996.The European HDR programme 1992-1995). 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 from S. Bourouis (Sismicité induite et comportement mécanique d'un massif granitique fracturé par injection d'eau). 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

Catalogue of microseismicity recorded at Soultz-sous-Forêts during 1994 production and injection tests. Calculated by the CSMA. Number of events: 211. Time period: 20:59:27 16/06/1994 to 23:38:12 11/07/1994. The data parameters are the following: Column 1: Seismic ID Column 2: Date Column 3: Time Column 4: Easting from GPK1 wellhead * Column 5: Northing from GPK1 wellhead * Column 6: Depth from GPK1 wellhead * Column 6: Latitude WGS84 ** Column 7: Longitude WGS84 ** Column 8: Elevation WGS84 ** 143 events from this catalogue are in the other microseismic catalogue of 1994 (available https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Catalogue) as well.

In 1996, three new accelerometers (4-component sensors) built by the CSMA and one hydrophone were deployed. As in past years, the 4-component sondes were located in boreholes 4616 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4616), 4601 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4601) and 4550 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4550) within the granite and the hydrophone was deployed in EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1). Unlike the previous episodes, the accelerometers were not grouted in the boreholes. The X,Y,Z coordinates in the file refer to the local coordinate system with the GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1) wellhead as origin: X: Easting in meters from GPK1 wellhead (toward UTM32 East) Y: Northing in meters from GPK1 wellhead (toward UTM32 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 CSMA report for Socomine by Jones and Jupe, 1997 (Microseismic results from the Soultz 1996 experimental programme). The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system. Last update of data: 16/02/2021

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);
