  1. 138. Bedretto Deep Underground Laboratory for Geoenergies – a new interdisciplinary research facility
    Katrin Plenkers

    Topic 4: Resource Development
    Oral

    The Bedretto tunnel in Ticino, Southern Switzerland has been identified to provide ideal conditions for underground in-situ experiments on the meso-scale related to geo-energies. The tunnel is located in the Rotondo Granite and comes with 1’000m plus overburden rock mass, for this reason providing a setting that is similar to typical deep reservoirs.
    The Bedretto tunnel is a 5km long side...

  2. 109. Modeling of High-Enthalpy Geothermal Projects in Fractured Reservoirs
    Mr Yang Wang (TU Delft)

    Topic 4: Resource Development
    Oral

    In general, high-enthalpy geothermal systems are characterized by a presence of vapor or coexistence of vapor-liquid phases. There is a complex phase transition (condensation) process during its development with cold water re-injection. Also, high-enthalpy geothermal reservoirs either contain naturally developed fractures or need induced fractures for fluid to flow at economically relevant...

  4. 133. Impact of a partly sealed fault on hydro-mechanical properties of a granite reservoir
    Dr Guido Bloecher (EOST-IPGS, Université de Strasbourg/CNRS, Strasbourg, France)
    10/9/19, 5:15 PM
    Topic 4: Resource Development
    Oral

    The fluid flow in Enhanced Geothermal Systems (EGS) is dominated by hydraulically stimulated fractures and faults which are the key elements of their hydraulic performance and sustainability. At the fault scale, the flow performance is influenced by the aperture distribution which is strongly dependent on the fault roughness, the geological fault sealing, the relative shear displacement, and...
