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...
متن کاملReducing Cost and Environmental Impact of Geothermal Power through Modeling of Chemical Processes in the Reservoir
Geothermal power generation and mineral extraction from geothermal brines are affected by chemical processes within the reservoir. Until recently, numerical simulation technology for geothermal systems could not handle most chemical processes, except for tracking total salinity, one or two noncondensable gases, and non-reactive tracers. The Lawrence Berkeley National Laboratory (LBNL) has devel...
متن کاملStochastic 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...
متن کاملHow do permeable fractures in the Triassic sediments of Northern Alsace characterize the top of hydrothermal convective cells? Evidence from Soultz geothermal boreholes (France)
Background: The thermal regime of the Upper Rhine Graben (URG) is characterized by a series of anomalies near Soultz-sous-Forêts (France), Rittershoffen (France), and Landau (Germany). These temperature anomalies are associated with groundwater circulation in fractures and faults distributed in the Cenozoic and Mesozoic sedimentary cover associated with and connected to fractures originating de...
متن کاملFracture Mapping in the Soultz-sous-Forêts geothermal field from Microearthquake relocation
In 2003, a massive hydraulic fracturing experiment was carried out at the European Geothermal Hot Dry Rock site at Soultz-sous-Forêts, France. The two week injection of water generated a high level of microseismic activity. About 90,000 microearthquakes were triggered during and after this fluid injection. Of these, 21,000 events, detected at all stations, were located individually with a grid ...
