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

The downhole seismological network in 1993 consisted of three accelerometers (4-component sensors) built by the CSMA and one hydrophone. The 4-component sondes were deployed 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) ( at depths of around 1500m within the granite and were grouted in place. The hydrophone was deployed in EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1) at a depth of around 2000m (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 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 report R 39025 of the BRGM by Hulot et al., 1996 (Testing the hodogram method on the 1993 Soultz microseismic data). The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system.

The downhole seismic network in 2000 consisted of three accelerometers (4-component sensors) built by the CSMA and two hydrophones. The two first accelerometers were placed in boreholes 4550 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4550) and 4601 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4601) and were assumed to have the same locations as in 1996. The last one was placed in OPS4 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-OPS4), an additional observation well drilled in early 2000 to improve the efficiency of the network. The three accelerometers were deployed at around 1500 m depth. The hydrophones were deployed much deeper at around 2000 m depth in borehole EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1) and at 3500 m depth in borehole GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1). The detection of seismic events was performed by trigerring. Each recorded signal has a duration of 2 s. 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 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 Semore Seismic report for Socomine by B. Dyer, 2001 (Soultz GPK2 stimulation June/July 2000. Seismic monitoring report). The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system. Last update of data: 11/06/2021

In 1990/1991, an old oil well, EPS1 has been deepened and cored to characterize the granite reservoir and perform some deep hydraulic tests in view of a future experimental doublet. Unfortunately, the well had an important not controlled deviation and could not reach the expected depth. However, it was cored from 930 m to the bottom hole at 2227 m depth and provided a lot of scientific data.
