    • Geomechanical response of fractured reservoirs 

      Zareidarmiyan, Ahmad; Salaridad, Hossein; Vilarrasa Riaño, Víctor; De Simone, Silvia; Olivella Pastallé, Sebastià (2018-12)
      Article
      Accés obert
      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
      Accés obert
      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)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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
      Accés obert
      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)
      Tesina
      Accés obert

    • 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
      Accés restringit per política de l'editorial
      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
      Accés restringit per política de l'editorial
      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
      Accés restringit per política de l'editorial
      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
      Accés obert
      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 modeling of hidraulic simulation in a deep geotermal reservoir 

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

    • Thermo-hydro-mechanical impacts of carbon dioxide (CO2) injection in deep saline aquifers. 

      Vilarrasa Riaño, Víctor (Universitat Politècnica de Catalunya, 2012-07-20)
      Tesi
      Accés obert
      Los procesos termo-hidro-mecánicos relacionados con el almacenamiento geológico de carbono deben ser entendidos y cuantificados para demostrar a la opinión pública de que la inyección de dióxido de carbono (CO2) es segura. ...
