Episode: 2020 Stimulation Geoven geothermal project at Vendenheim

Description

During the interruption, at the end of 2019, the GT2 well was deepened. The tests were authorized in September 2020, and new tests were carried out.
These tests were stopped on 28/10/2020 after a new period of seismicity with an event of magnitude 2.8 Mlv on October 28, and 3.6 Mlv on December 4, 2020.

Some of the data have been extrapolated from the Figures presented in the expert report, publicly available.

GeORG 3D Geological Model —Vendenheim

Dataset

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.

Geological sections from GeORG - Vendenheim

Dataset

The GeORG project (2008–2012) produced a 3D geological model of the Upper Rhine Graben and a comprehensive geoscientific database, including deep‑structure maps, temperature models, and geological cross‑sections accessible online. Several GeORG products around the Vendenheim geothermal site were extracted from the map viewer.
