  • 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)
    Article

    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 ...
  • Extension of CODE_BRIGHT to simulate non-isothermal CO2 injection in deep saline aquifers 

    Vilarrasa Riaño, Víctor; Olivella Pastallé, Sebastià; Silva Rojas, Orlando Enrique; Carrera Ramírez, Jesús (Universitat Politècnica de Catalunya. Departament d'Enginyeria del Terreny, Cartogràfica i Geofísica (ETCG), 2012)

  • 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 ...
  • Geomechanical stability of the caprock during CO2 sequestration in deep saline aquifers 

    Vilarrasa Riaño, Víctor; Olivella Pastallé, Sebastià; Carrera Ramírez, Jesús (2011)
    Article
    Open Access
    Sequestration of carbon dioxide (CO2) in deep saline aquifers has emerged as a mitigation strategy for reducing greenhouse gas emissions to the atmosphere. The large amounts of supercritical CO2 that need to be injected ...
  • Impacts of cold CO2 injection in deep saline aquifers on the rock mechanical integrity. 

    Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; SILVA, ORLANDO; Olivella Pastallé, Sebastià (2013)
    Conference report
    Restricted access - publisher's policy
    Injecting CO2 into aquifers at depths greater than 800 m brings CO2 to a supercritical state where its density is large enough to ensure an efficient use of pore space. However, CO2 may not be in thermal equilibrium with ...
  • Induced seismicity in geologic carbon storage 

    Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Olivella Pastallé, Sebastià; Rutqvist, Jonny; Laloui, Lyesse (2019-06)
    Article
    Open Access
    Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock ...
  • Numerical modelling of fluid flow and particle transport in a riugh rock fracture during shear 

    Vilarrasa Riaño, Víctor (Universitat Politècnica de Catalunya, 2005-06)
    Minor thesis
    Open Access
  • Semianalytical solution for CO2 plume shape and pressure evolution during CO2 injection in deep saline formations 

    Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Bolster, Diogo; Dentz, Marco (2013-01-16)
    Article
    Restricted access - publisher's policy
    The injection of supercritical carbon dioxide (CO2) in deep saline aquifers leads to the formation of a CO2 rich phase plume that tends to float over the resident brine. As pressure builds up, CO2 density will increase ...
  • Shear-induced flow channels in a single rock fracture and their effect on solute transport 

    Vilarrasa Riaño, Víctor; Koyama, T.; Neretnieks, I.; Jing, L. (2011)
    Article
    Restricted access - publisher's policy
    The effect of mechanical shearing on fluid flow anisotropy and solute transport in rough rock fractures was investigated by numerical modeling. Two facing surfaces of a rock fracture of 194mm×194mm in size were laser ...
  • 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. ...
  • Thermal effects on geologic carbon storage 

    Vilarrasa Riaño, Víctor; Rutqvist, Jonny (2017-02-01)
    Article
    Open Access
    One of the most promising ways to significantly reduce greenhouse gases emissions, while carbon-free energy sources are developed, is Carbon Capture and Storage (CCS). Non-isothermal effects play a major role in all stages ...
  • Thermo-hydro-mechanical impacts of carbon dioxide (CO2) injection in deep saline aquifers.
