  • Deep enclosures versus pumping to reduce settlements during shaft excavations 

    Pujades Garnes, Estanislao; Vázquez Suñé, Enric; Carrera Ramírez, Jesús; Vilarrasa Riaño, Víctor; De Simone, Silvia; Jurado Elices, Anna; Ledesma Villalba, Alberto; Ramos Schneider, Gonzalo; Lloret Morancho, Antonio (2014-02-04)

    Deep excavations in aquifers may be constructed by combining pumping with the cut and cover method. The enclosures are often deepened more than structurally needed, in order to diminish the risk of heave or fluidisation ...
  • Geomechanical response of fractured reservoirs 

    Zareidarmiyan, Ahmad; Salaridad, Hossein; Vilarrasa Riaño, Víctor; De Simone, Silvia; Olivella Pastallé, Sebastià (2018-12)
    Article
    Open Access
    Geologic carbon storage will most likely be feasible only if carbon dioxide (CO2) is utilized for improved oil recovery (IOR). The majority of carbonate reservoirs that bear hydrocarbons are fractured. Thus, the geomechanical ...
  • Induced seismicity in enhanced geothermal systems : assessment of thermo-hydro-mechanical effects 

    De Simone, Silvia (Universitat Politècnica de Catalunya, 2017-03-29)
    Doctoral thesis
    Open Access
    Micro-seismicity, and especially felt seismicity, induced by Enhanced Geothermal Systems (EGS) operations is a matter of scientific interest, not only because of the related risks and concerns, but also because the ...
  • Numerical advances to simulate shear failure and tensile failure due to hydraulic fracturing operations 

    Gómez Castro, Berta María; De Simone, Silvia; Carrera Ramírez, Jesús (2017)
    Conference report
    Open Access
    In recent years, some geological applications like the CO2 storage or the hydraulic fracturing have attracted the attention not only of the scientific community but also of the general public. One of the reasons of the ...
  • Thermal coupling may control mechanical stability of geothermal reservoirs during cold water injection 

    De Simone, Silvia; Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Alcolea Rodríguez, Andrés; Meier, Peter (2013-01-17)
    Article
    Restricted access - publisher's policy
    Hydraulic stimulation and geothermal reservoir operation may compromise the rock mechanical stability and trigger microseismic events. The mechanisms leading to this induced seismicity are still not completely understood. ...
  • Thermo hydro mechanical modeling of hidraulic simulation in a deep geotermal reservoir 

    De Simone, Silvia; Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Alcolea Rodríguez, Andrés; Meier, Peter (2013)
