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).

VDH-GT1 is the first well drilled within the framework of the Geoven geothermal project at Vendenheim. The drilling of the well began in June 2017 and reached a final length of 5408 m in March 2018. A second leg at VDH-GT1 was drilled between February and September 2019 and a third between June and August 2020 to 5447 m (4644m TVD). VDH-GT1 will be used as production well. Location of the VDH-GT1 wellhead (in WGS84): Latitude: 48.8970080 Longitude: 7.9387218 Altitude: 134m At the present time, the Geoven project (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDHD) is still in development and this description may change.

VDH-GT2 is the second well drilled within the framework of the geothermal project Geoven at Vendenheim. The well was drilled from August 2018 to February 2019 to 5308 m (4417m TVD), and prolongated between November 2019 and February 2020 to 6312m (5011m TVD). VDH-GT2 will be used as injection well. Location of the VDH-GT2 wellhead (in WGS84): Latitude: 48.8970198 Longitude: 7.9386127 Altitude: 134m At the present time, the Geoven project (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDHD) is still in development and this description may change.

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.
