The microseismic monitoring at Rittershoffen began 6 months before any drilling. Four permanent stations were deployed at the surface in 2012 and completed the network of eight surface stations from the Soultz-sous-Forêts network. The permanent network is composed of one or three-components seismometers. A temporary network of 31 stations (TOPASE network) was deployed from June 2013 to November 2014 to improve the dectection and location of the seismic monitoring during the field development operations. The stations of the temporary network were three-component seismometers belonging to the Geophysical Instrument Pool Potsdam (GIPP) of the GFZ German Research Centre for Geosciences. Easting and northing in the file refer to the extended Lambert II Cartesian system. The latitude and longitude in the WGS84 coordinate system have been derived from the extended Lambert II Cartesian system.

Geoven (http://www.geoven.fr) is a geothermal powerplant project led by Fonroche Géothermie now Arverne (https://arverne.earth/). The project is implemented on the site of the Rhenan Ecoparc at Vendenheim, north of Strasbourg. The geothermal powerplant produced 6 MW of electrical energy and 40 MW of thermal energy. To this end, two wells were used to draw the hot water and reinject it at more than 4000 meters deep. The two wells VDH-GT1 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/VDH-GT1) and VDH-GT2 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/VDH-GT2) had been drilled and some tests had been conducted (5 injectivity and productivity cycles between 02/2018 and 11/2019). A first interruption occured after a first period of seismicity (11/2019 – 01/2020, MLv=3.0 max) at Strasbourg and Vendenheim, to allow a third-party scientific expertise. During this period, the well was deepened of 450m to reach 5000m. New tests were authorized starting 10/2020, but were stopped on 28/10/2020 after a new period of seismicity with quake reaching 3.6MLv (04/12/2020). Authority decided on 07/12/2020 to definitely stop the project. Another earthquake of 3.9 ML (https://www.franceseisme.fr/donnees/intensites/2021/210626_0300/Rapport_BCSF-RENASS_2021R1_EVT210626-DPT67.pdf) occured on 26/06/2021. Authorities set up a committee of experts that delivered a first report (https://www.bas-rhin.gouv.fr/Politiques-publiques/Environnement/Geothermie/Rapport-du-comite-d-experts-cree-en-appui-a-l-administration-sur-la-boucle-geothermique-GEOVEN).

In June and July 1994, the hydraulic experimental programme consisted of a production test and an injection test at GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1). During the production test in June, EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1) was used as injection well. A total of 6200 m3 of fluid were produced during the test. Then the injection test in July was intended to determine the injectivity of the stimulated fracture system as a function of the flowrate. A total of 9600 m3 of water were injected at various flowrates during the test (Baria, R., 1996.The European HDR programme 1992 - 1995). Dates of the different tests of the 1994 hydraulic programme: - Production test at GPK1: from 15:58 16/06/94 to 10:15 28/06/96 - Injection test at GPK1: from 11:06 05/07/94 to 14:56 13/07/96 The Episode contains the following datasets: - Microseismic downhole network - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Downhole_network); - Microseismic catalogue of the downhole network from CSMA - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Catalogue_all); - Microseismic catalogue with moment magnitude of the downhole network from CSMA - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Catalogue); - Flow logs - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Flow_logs_gpk1); - Temperature logs - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Temperature_logs_gpk1); - Hydraulic data - Soultz-sous-Forêts 1994 Hydraulic Tests (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFC1994-Hydraulic);

The ECOGI powerplant (https://geothermie.es.fr/en/references/projet-ecogi) is a geothermal powerplant designed by ÉS-Géothermie and located at Rittershoffen in northern Alsace, 7 km southeast of Soultz-sous-Forêts. The geothermal plant of Rittershoffen is operating since mid-2016 and produces 24 MWth of thermal power, with a production temperature of 170 °C. The geothermal heat production is directly used by a biorefinery located at Benheim. Two wells ensure the production and reinjection of the geothermal fluid. The development of the deep geothermal field took place between 2012 and 2014. Several earthquakes occurred between 2012 and 2014 during the drilling of the two wells GRT-1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/RIT-GRT1) and GRT-2 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/RIT-GRT2) and some of the hydraulic tests realized on site. The induced seismicity was recorded by a permanent and a temporary seismic network.
