The aim of the Soultz-sous-Forêts Geothermal Power Plant (SGPP, Upper Rhine Graben, France) is to optimize the exploitation of a fractured granitic reservoir (Figure 1), while minimizing environmental issues. In MEET project, this demo-site is tested for enhancing energy production. To this aim, the temperature of the reinjected fluid is to be lowered from 70°C…
A field campaign based on the water sampling of 50 springs was realized by the Geological Survey of Belgium (GSB) between October 2019 and March 2020. The aim of studying spring water in the near field (in the Havelange drilling area) and in the far field (near the analogues sites) was to determine the mineral…
The H2020 Multidisciplinary and multi-context demonstration of EGS exploration and Exploitation Techniques and potentials (MEET) is a European project, which aims at enhancing demonstration of geothermal energy production throughout Europe. Part of the MEET project is dedicated to characterization of geothermal reservoirs analogues in order to better understand the behavior of target exploited reservoir, especially…
In the frame of the H2020 MEET project, a fibre-optic cable has been deployed on July 30th in the 2.2 km-deep observation well EPS-1 in the Soultz-sous-Forêts geothermal site. Prior to field operation, ESG was in charge of the risk assessment, technical specifications, tender analysis and well logging company selection. This descent, the second one…
Most of geothermal plant are designed with transportation pipes connecting production or injection wells to the plant a few kilometres away. Transporting very hot geothermal water or steam is a technical challenge in term of thermal expansion management and corrosion issues. These pipes are most of the time above ground like in Iceland or Tuscany.…
