- Investigation of a deep offshore CO2 storage in the Celtic Sea and the Bay of Biscay area.
- Influence of N2 and CH4 on liquid density and on gas hydrate equilibrium in the high pressure range.
- First estimates of the CO2 storage capacity in the French EEZ and comparison with the Paris Basin capacity.
