2D reactive transport modeling of the interaction between a marl and a CO2-rich sulfate solution under supercritical CO2 conditions
Dávila Ordóñez, Maria Gabriela; Luquot, Linda; Soler Matamala, Josep M.; Cama Robert, Jordi; Luquot, Linda (John Gale, 2016-11-01)
Article
Accés obertThe circulation of CO2-rich solutions through fractured marl cores (caprock) under different flow rates and supercritical CO2 conditions (PTotal = 150 bar, pCO2 = 61 bar and T = 60 °C) led to mineral changes caused mainly ... -
Efficiency of magnesium hydroxide as engineering seal in the geological sequestration of CO2
Dávila Ordóñez, Maria Gabriela; Cama Robert, Jordi; Galí i Medina, Salvador; Luquot, Linda; Soler Matamala, Josep M. (John Gale, 2016-05)
Article
Accés obertInjection of CO2 at depth will cause the acidification of groundwater. As a preliminary study for the potential use of MgO as an alternative to Portland cement in injection wells, MgO carbonation has been studied by means ... -
Geochemical kinetics during CO2 sequestration : the reactivity of the Hontomín caprock and the hydration of MgO
Dávila Ordóñez, Maria Gabriela (Universitat Politècnica de Catalunya, 2015-11-06)
Tesi
Accés obertA test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone. The reservoir rock is a deep saline aquifer, which contains a NaCl- and ... -
Interaction between a fractured marl caprock and CO2-rich sulfate solution under supercritical CO2 conditions
Dávila Ordóñez, Maria Gabriela; Luquot, Linda; Soler Matamala, Josep M.; Cama Robert, Jordi (John Gale, 2016-05)
Article
Accés obertGeological CO2 sequestration at pilot-plant scale will be developed at Hontomin (Spain). CO2 will be injected into a limestone reservoir that contains a NaCl- and sulfate-rich groundwater in equilibrium with calcite and ...
