Centre de données de Géothermie Profonde

The Deep Geothermal Data Centre (CDGP) is a data center managed by University of Strasbourg, dedicated to the collection, preservation and distribution of data from deep geothermal projects in Alsace (France).

The CDGP distributes various types of data: seismological, hydraulic, geological, etc.

The CDGP is the French national node of the EPOS Thematic Core Service Anthropogenic Hazards (TCS-AH).
This European infrastructure provides open access to multidisciplinary datasets on induced seismicity.
Through the EPISODES Platform, CDGP data are shared with the European scientific community, enabling advanced processing and visualization tools.

BCSF-Rénass

The Bureau central sismologique français - Réseau national de surveillance sismique (BCSF-Rénass) is a component of the National Observation Action (ANO) “Seismology” of the National Observation Service (SNO) “Solid Earth”, labelled by the CNRS-INSU

The BCSF-Rénass, located in Strasbourg and managed by the Ecole et Observatoire des Sciences de la Terre (EOST), is in charge of:

- monitoring seismic activity in mainland France and in border areas,

- discriminating between natural and anthropogenic seismicity (of human origin or induced by man: mining activities, explosions, demining, exploitation of the subsoil, notably geothermal energy producti…

Episode: 1995 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Collection

The 1995 hydraulic program tested GPK‑2 and its ability to circulate with GPK‑1. After low injectivity was confirmed, short‑ and long‑term stimulations were performed, followed by post‑fracturing tests and three brief circulation experiments between the two wells.

Episode: 1993 Stimulation Soultz-sous-Forêts

Collection

During the 1993 program, GPK‑1 was deepened to 3590 m and subjected to large‑scale hydraulic stimulations to investigate major natural fractures. Across two main tests injecting a total of 44 000 m³ of water, about 18 700 microseismic events were detected, with activity monitored by both downhole and surface networks.

Episode: Geoven geothermal project at Vendenheim

Collection

The Geoven project in Vendenheim aimed to produce geothermal power from two deep wells, but repeated induced seismicity during drilling and testing led authorities to permanently shut it down in December 2020, with another ML 3.9 event occurring in June 2021.

Velocity model and static corrections used by N. Cuenot to locate seismic events acquired from the downhole and surface network - Soultz-sous-Forêts 2000 Stimulation

Dataset

Velocity models from Cuenot’s thesis were built from GPK1 sonic logs and calibration shots, first as an initial model for preliminary locations, then refined into the final model.
