The Condorcet heat delivery project aims delivering geothermal heat from an oilfield to a high school located in Arcachon, France. This area of France is located in a large sedimentary basin, hence the presence of numerous oilfields, whose production started in the 60’s. Today most of them are exploited by VERMILION. These so- called “mature”…
Göttingen is not within the type of area traditionally considered to have high geothermal potential. Moreover, there is currently little information about the geology of the target rocks at 3000 to 5000 m depths, which consist of complexly folded and thrusted metamorphic rocks. Such a geothermal target has not previously been exploited for geothermal energy.…
Numerical model from a geothermal site Researchers at Technische Universität Darmstadt are trying to develop computational models to predict the heat extraction from one of the most investigated MEET demonstration sites: Soultz-sous-Forêts. Possibility of colder fluid injection than the current operational fluid shows potential economic advantages. Geothermal field development may trigger small earthquakes and some…
GIM-labs have performed a complete sensitivity study to assess the ability of the Full Wave Inversion (FWI) method to detect, delineate and further characterize faults in the granitic geothermal reservoir of Soultz-sous-Forêts. The objective of this study is to study the potential of the FWI applied to the crystalline rocks of Soultz. Their approach consists…
Large scale fluid transport within the Earth’s crust is predominantly controlled by planar void space like fractures and crack networks. Characterizing the time dependent hydro-mechanical properties of such structures, therefore, is of paramount importance for an economic use of geo-reservoirs for energy (power and/or heat) provision. This particularly applies to Enhanced Geothermal Systems (EGS), where…
Almost all geology undergraduates are taught about Mohr diagrams because they are a simple and convenient way of understanding the relationships between stresses and fluid pressure (effective stresses), the mechanical properties of the rock and the resultant fracturing. Sadly, most geologists seem to forget those lessons and do not appreciate how Mohr diagrams can be…
The MEET consortium is happy to announce the edition of a Special Issue “Enhanced Geothermal Systems and other Deep Geothermal Applications throughout Europe: The MEET Project” in Geosciences, a journal published by MDPI This Special Issue aims at compiling the most recent results obtained by the 16 academic and industrial partners, coming from 5 countries,…
During the past year, the MEET demosites in Iceland, at Grásteinn and Krauma, have drawn quite the attention to possibilities of using Organic Rankine Cycle(ORC) technology to produce electricity from low-temperature geothermal sources in Iceland. The first demonstration site, Grásteinn, is a small family farm in southeastern Iceland, close to the town of Hveragerði, which…
