Análisis de riesgos en proyectos de almacenamiento geológico de CO2: selección de emplazamientos adecuados, costes y análisis de los riesgos asociados a este tipo de proyectos
(2011)
Book
Restricted access - publisher's policyUna de las causas del cambio climático es la emisión antropogénica de gases de efecto invernadero, principalmente el CO2. Para reducir estas emisiones una de las opciones que existen es el almacenamiento geológico de CO2. ... -
Dissolved CO2 effect on the reactivity of the Hontomín reservoir rocks (limestone and sandstone)
(Universitat Politècnica de Catalunya, 2015-03-13)
Doctoral thesis
Open AccessA test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone (80-85%) and sandstone (15-20%). The reservoir rock is a deep saline aquifer ... -
Feasibility study on CO2 capture and storage in silicate substrates
(Universitat Politècnica de Catalunya, 2016-07)
Master thesis (pre-Bologna period)
Open AccessThe increasing CO2 concentrations in the atmosphere are attributed to the rising consumption of fossil fuels for energy generation. Mineral carbonation technologies methods are needed to prevent the global warming bellow ... -
Induced seismicity in geologic carbon storage
(2019-06)
Article
Open AccessGeologic 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 ... -
Injection of CO2-saturated brine in geological reservoir: a way to enhanced storage safety
(John Gale, 2016-11)
Article
Open AccessInjection of free-phase supercritical CO2 into deep geological reservoirs is associated with risk of considerable return flows towards the land surface due to the buoyancy of CO2, which is lighter than the resident brine ... -
Insights into the direct carbonation of activated lizardite: the identification a poorly reactive amorphous Mg-rich silicate phase
(John Gale, 2020-09)
Article
Open AccessThis work aims to shed light on the yet unanswered question regarding the limited carbonation yield of activatedlizardite via direct carbonation. Two amorphous Mg-rich silicate phases were identified upon activation. A ... -
Modelling acid attack of oilwell cement exposed to carbonated brine: effect of specimen geometry on experimental results
(2019)
Conference report
Open AccessIn recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oilwell cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil ... -
Phase evolution during accelerated CO2 mineralization of brucite under concentrated CO2 and simulated flue gas conditions
(Elsevier, 2020-04)
Article
Open AccessExperimental work on the carbonation of brucite has been carried out in the temperature and pressure ranges of 50-120 °C and 1-10 bar respectively, using concentrated CO2 and simulated flue gas. At 120 °C hydro- magnesite ... -
The role of advection and dispersion in the rock matrix on the transport of leaking CO2-saturated brine along a fractured zone
(Elsevier, 2016-12)
Article
Open AccessCO2 that is injected into a geological storage reservoir can leak in dissolved form because of brine displacement from the reservoir, which is caused by large-scale groundwater motion. Simulations of the reactive transport ... -
Zero-thickness interface model with chemical degradation by acid attack
(2019)
Conference report
Open AccessCarbon dioxide (CO2) storage in abandoned oil/gas reservoirs is considered a viable alternative to reduce greenhouse gas emissions to the atmosphere. An important element of the risk associated with long-term CO2 storage ...
