Geochemical study of the reactivity of a carbonate rock in a geological storage of CO2 : Implications of co-injected gases
Stéphane Renard,Jérôme Sterpenich,Jacques Pironon,Pierre Chiquet,Marc Lescanne,Aurélien Randi +5 more
TL;DR: In this paper, the reactivity of a carbonate rock in the presence of a gas containing CO 2 and co-injected gases is investigated and it is shown that the main mineral transformations of the rocks are due to the co-insjected gases SO 2 and O 2 despite their low concentration (less than 4%), these transformations should have different impacts on the petrophysical properties of the rock such as porosity and permeability.

Role of Impurities on CO2 Injection: Experimental and Numerical Simulations of Thermodynamic Properties of Water-salt-gas Mixtures (CO2 + Co-injected Gases) Under Geological Storage Conditions
Jérôme Sterpenich,Jean Dubessy,Jacques Pironon,Stéphane Renard,Marie-Camille Caumon,Aurélien Randi,Jean-Noël Jaubert,Eric Favre,Denis Roizard,Marc Parmentier,Mohamed Azaroual,Véronique Lachet,Benoit Creton,Teddy Parra,Elise El Ahmar,Christophe Coquelet,Vincent Lagneau,Jérôme Corvisier,Pierre Chiquet +18 more
TL;DR: In this article, the role of impurities on CO 2 injection in a geological storage is investigated, where the authors present Gaz Annexes concerning acquisition of PVT experimental and pseudo-experimental data to adjust and validate thermodynamic models for water / gas / salts mixtures as well as the possible influence of SO 2 and NO on the geological storage of CO 2.

Emmanuel Jobard,Emmanuel Jobard,Jérôme Sterpenich,Jérôme Sterpenich,Jacques Pironon,Jacques Pironon,Jérôme Corvisier,Jérôme Corvisier,Mathieu Jouanny,Mathieu Jouanny,Aurélien Randi,Aurélien Randi +11 more
TL;DR: In this paper, the reactivity of crushed oolithic limestone was investigated in the presence of high pressure CO 2 and a high thermal gradient (100-35°C in a 78 cm long tubular reactor) for 30 days.

Effect of a thermal gradient on iron-clay interactions
Marie-Camille Jodin-Caumon,Régine Mosser-Ruck,Davy Rousset,Aurélien Randi,Michel Cathelineau,Nicolas Michau +5 more
TL;DR: In this paper, a tube-in-tube experimental device was developed and an 80-300oC thermal gradient was applied to a mixture of MX80 bentonite, metallic Fe (powder and plate), magnetite, and fluid over periods of 1 to 10 months.

Experimental Modelling of the Caprock/Cement Interface Behaviour under CO2 Storage Conditions: Effect of Water and Supercritical CO2 from a Cathodoluminescence Study
Emmanuel Jobard,Jérôme Sterpenich,Jacques Pironon,Jérôme Corvisier,Aurélien Randi +4 more
- 18 May 2018
TL;DR: In this paper, the results from an experimental modelling of the evolution of a caprock/cement interface under high pressure and temperature conditions were discussed. But the authors did not consider the impact of water on the transport mechanisms of dissolved species and thus on the location of mineral precipitations.
