Full textMineral storage of carbon dioxide in the form of geologically stable carbonates is an option for mitigating the atmospheric CO2 increase. The purpose of this thesis has been to study carbonate formation in basic and ultrabasic rocks under high pressure high temperature possible CO2 injection conditions. First, data on siderite dissolution, a reaction limiting CO2 mineral storage, have been acquired by x-ray absorption spectroscopy under high pressures and high temperatures. A dissolution rate law, an activation energy and solution speciation data are given. These experiments have allowed to test the potential for these kinds of studies of batch microreactors mounted on synchrotron beamlines. Then, a laboratory experiment aimed at mimicking CO2 injection in basic and ultrabasic rocks at 90°C and 280 bar CO2 pressure is shown. Carbonatation by dissolution/precipitation of peridotites, basalts and serpentinites yields zoned siderites/ankerites/magnesites with mineral storage rates, depending on the substrate rock, of few percents per year. Finally, in order to study cases with high carbonatation rates, an experimental study on olivines, pyroxenes and serpentines has been relalized at 400-500°C and 1-1. 7 kbar. Mineral storage rates of several percents per hour have been measured. The importances of water fugacities and salinities have been evidenced and a stoichiometric coupling between carbonate production and olivine serpentinization has been shown. A methodology based on carbon isotopic analyses has been developed for establishing mass balances. It suggests that small but significant quantities of reduced carbon are formed in these experiments

Full textSince the mid-90s, in situ mineralization of CO2 has been considered as a safe and efficient solution to mitigate its anthropogenic emissions to the atmosphere. It is to recover the CO2 emitted by some industries and trap it in the mineral form (carbonates) in mafic and ultramafic aquifers (e.g. basalts and peridotites). The carbonation of CO2 has been widely described in natural systems where it occurs through a series of complex chemical reactions coupled to the transport of reactive species in the fluid. Numerous experiments have been conducted in batch reactors over the past fifteen years to better understand the physico-chemical parameters controlling the carbonation of (ultra-)mafic rocks. But few studies have further characterized the coupling reactive-transport processes during the injection and in situ mineralization of CO2 in these rocks.This work aims to meet 3 main objectives: (i) characterize changes in reaction paths during the injection of CO2 in (ultra-)mafic systems, (ii) measure the feedbacks effects of chemical reactions on the hydrodynamic rock properties and (iii) quantify the efficiency and sustainability of such processes over long time periods. It is based on the development of experimental protocols to (i) reproduce the injection of CO2 into (ultra-)mafic rocks and (ii) characterize the reactions using a series of geochemical and analytical tools from the atomic to the centimetric scale. Three series of reactive percolation experiments have been performed on (ultra-)mafic aggregates from relatively simple (olivines from San Carlos and Hawaii) to more complex samples (basalts from Stapafell) under in situ P-T-containment conditions (Ptot=10-25 MPa; T=180-185°C; Pcont=15-28 MPa).The results allowed us to differentiate several reactions paths in these systems depending on the fluid transport, rock porosity, local hydrodynamic properties, mineralogy and/or local changes in the fluid composition. Mass balance calculations have revealed an efficient mineralization of CO2 in the samples. It is controlled by the chemical and the hydrodynamic properties of the rock at the pore scale. But some reactions associated with the alteration of (ultra-)mafic rocks (e.g. hydration) have negative feedbacks effects on the reservoir rock properties (porosity and permeability) that may compromise the sustainability of CO2 storage in natural aquifers in the long term.These new supporting data will allow numerical models to better simulate the carbonation of (ultra-)mafic rocks knowing the hydrodynamic properties and the structural heterogeneities of the reservoir. They also suggest that a better control of some injection parameters, such as the flow injection rate and the injected fluid composition (e.g. pCO2), would improve the rate and yield of CO2 mineralization in these systems
