Two-dimensional THMmodelling of the large scale natural hydrothermal circulation at Soultz-sous-Forêts

Impact of Induced Thermal Stresses During Circulation Tests in an Engineered Fractured Geothermal Reservoir Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France

Impact of Induced Thermal Stresses during Circulation Tests in an Engineered Fractured Geothermal Reservoir: Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France — The wider concept of hot fractured rock geothermal energy is put forward to overcome the natural limitations of classic geothermal fields. A suite of numerical modules based on a disc...

The Soultz-sous-Forêts’ Enhanced Geothermal System: A Granitic Basement Used as a Heat Exchanger to Produce Electricity

Steps towards a Comprehensive Thermo-hydraulic Analysis of the Hdr Test Site Soultz-sous-forêts

During the exploration of the HDR test site Soultz-sousForêts (France) numerous unexpected thermal and hydraulic features have been encountered. The HDR reservoir at the Soultz-sous-Forêts site is targeted in a granitic horst zone bounded by subvertical N-S trending normal faults. The high surface heat flow at HDR test site, Soultz-sous-Forêts, being a main reason for its selection dropped from...

Microstructural and petrophysical properties of the Permo-Triassic sandstones (Buntsandstein) from the Soultz-sous-Forêts geothermal site (France)

Geothermal projects in the Upper Rhine Graben aim to harness thermal anomalies that have arisen due to hydrothermal circulation within the granitic basement and the overlying Permo-Triassic sedimentary units. We present here a systematic microstructural, mineralogical, and petrophysical characterisation of the lowermost unit of this Permo-Triassic sedimentary succession—the Buntsandstein—sample...

Stochastic Permeability Estimation for the Soultz-sous-forêts Egs Reservoir

Information on the distribution of permeability at depth is of primary concern in geothermal reservoir engineering. Based on a tracer circulation test performed at the European Enhanced Geothermal System (EGS) test site at Soultz-sous-Forêts, France, three different inversion methods are applied and studied with respect to their potential for estimating the permeability distribution: A fully ph...
