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: 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.

Episode: 1994 Hydraulic Tests Soultz-sous-Forêts

Collection

During June–July 1994, GPK‑1 underwent a production test followed by an injection test. About 6 200 m³ of fluid were produced in June using EPS‑1 as the injection well, and 9 600 m³ of water were injected in July at varying flowrates to assess the injectivity of the stimulated fracture system.

Episode: 1988 Stimulation Soultz-sous-Forêts

Collection

The Soultz‑sous‑Forêts HDR site was selected in 1986, leading to the drilling of the 2000 m‑deep GPK‑1 well. A 1988 low‑rate injection test triggered microseismicity, with events migrating deeper than the injection zone.

Dataset in collection Episode: Geoven geothermal project at Vendenheim

The GeORG project provides a 3D geological model of the Upper Rhine Graben. The BRGM distributes the French section, and a 10 km cut‑out around Soultz‑sous‑Forêts was extracted, including major lithological interfaces (Plio‑Quaternary to Hercynian), salt diapirs, and faults.
