  • 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 ...
  • Modeling evaporation processes in a saline soil from saturation to oven dry conditions

    Article
    Open Access
    Thermal, suction and osmotic gradients interact during evaporation from a salty soil. Vapor fluxes become the main water flow mechanism under very dry conditions. A coupled nonisothermal multiphase flow and a reactive ...
