Conceptual thermo-hydraulic modelling of the Göttingen demo-site to gain understanding of behaviour of potential metamorphic EGS reservoirs

The first conceptual model for Göttingen demo site has been developed based on the Discrete Fracture Network (DFN) approach as shown in Figure 1 by MEET-partner Technical University of Darmstadt (TUDa). In the first strongly simplified conceptual model set-up, 80 fractures are randomly placed inside a 200 m cube and bounded by 50 m thick…

Cornwall and UDDGP demosite – petrophysical characterization of outcrop analogue samples: from field to core scale

With the ambition to increase the share of clean energy in United Kingdom’s energy portfolio, Cornwall has been the focus of deep geothermal resource studies starting from 1980s with the Rosemanowes Hot Dry Rock project. Today our associated partner the United Downs Deep Geothermal Power Project (UDDGP), the first industrial deep geothermal power project of…

Scaling phenomenon at Soultz in a small prototype exchanger

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…

Analogy between Death Valley and the Upper Rhine graben

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…

Deployment of fibre-optic wireline at Soultz-sous-Forêts

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…
